Staff were rude and unhelpful - try to scam you into buy 100 euro sunbeds and expensive taxi transfers when the sunbeds are 25 and taxis are 25 euros if official. They only give beach towels every few days. Staff at breakfast were miserable. The breakfast was really poor - bad quality food and not great choice, barely any fruit, literally just eggs upon eggs. The room was decent and had great A/C. Did not really use the pool areas but they were nothing special and the beach is amazing. Location was great, right on the beach. The beach is the best beach in Mykonos in my opinion and I went to 6 or so including super paradise beach (which was good not great).

Great beach views. Great location close to lots of things.

Pros: The biggest advantage of this hotel is the location. It has a relaxing resort-style atmosphere right by a beautiful beach, away from the busy Old Town Mykonos. Transportation is very easy, with a direct bus from Old Town to the beach area for only €2.20, taking about 10–15 minutes. The beach area in front of the hotel has a great vibe, and the breakfast buffet was decent, offering basics like eggs, cheese, bread, vegetables, juice, and coffee. I was hoping to get more fresh fruits but it was mainly oranges and pears and they were not the greatest.. you are in Greece and you want to see great fresh fruits at least. Cons: The room was disappointing for the price of €200+ per night. Although I booked a standard queen room, it was located in a separate extension outside the main hotel building that felt more like a motel annex and did not match the online photos. The room had no proper window, only a small one facing the hallway, which caused noise and light issues. The bathroom setup was inconvenient, with only a handheld shower head, no actual mounted shower and no curtain or door, leaving water all over the floor after showering. There was also no proper closet, just a few hangers above the fridge. Another important detail: the beach sunbeds are not included and cost €40+ per person since they are operated separately from the hotel. Overall, the location and beach access are excellent, but the room quality and overall experience did not justify the high price.

Room was very clean, breakfast had a wide range of food, beach view was beautiful

The breakfast staff and the food was fantastic, our room did not overlook the beach but overlooked the swimming pool. All the staff at the Kosmoplaz Beach Hotel were fantastic, front desk, maids, the breakfast buffet staff. Everyone was the best, thanks for making our staff the best ever.

Clean and good hotel

Great hotel with a great location and right on the beach front, friendly & helpful staff, always kept clean and tidy which is much appreciated. The breakfast could be slightly better (a somewhat limited choice). It says that there's a gym and sauna, but there was no sign of it! It may be a case of they open up more as the season gets busier (as we went in April/early May). Also, there only seemed to be one restaurant but there's two listed on the page (again, this may have open when the summer season approaches).

Booked vacation for my mom's birthday as it was her dream to visit Greece.The Cosmoplatz hotel is cozy, quiet and located on nice beach.The staff is very nice and friendly. Especially I would like to notice front desk receptionist Guzel,who was very helpful and assisted my mom with navigation and all accomodations.Thank you for making my mom's birthday unforgettable experience! We'll definitely be back next time together and I would recommend this hotel for your vacation

The staff is very nice and friendly. The breakfast was amazing. The greek yogurt is something else!

Clean room. You need a car for staying here and move. To go to the beach you need to pay or find a spot.

It's supposed to be a boutique hotel for relaxing; the pool water should be warm, but it's unusable. It's certified at less than 5 degrees Celsius. Using it could cause hypothermia.

El hotel muy bonito , elegante bien ubicado pero pagamos por una habitación Delux y el sauna no estaba funcionando y el TV tuvo problemas las 2 noches que estuve

My stay at this hotel was extremely disappointing. There was ongoing construction throughout the property, which was never clearly communicated beforehand. To make matters worse, the elevator was not working, which was very inconvenient—especially when traveling with a disabled person. The entire place was filled with dust from the construction, making it feel unclean and uncomfortable. This hotel should not be accepting guests while in this condition. Save your money and stay somewhere else.

The hotel claims that the beach front it managed by a third-party company (I doubt it) the beach front of hotel is occupied with sunbeds and umbrellas belong to this company. That company charges arm and leg for a very low-quality food in order to let you to use the beachfront area.

4 stars for staff because management is not u

Really liked the area and the staff is great. WiFi is not the best just a heads up, which can be frustrating if you work remote. Also the beach beds in the photo are separate from the hotel, which i feel its important to note

The staff was exceptional. The location was amazing for everything we wanted to do.

This quaint beach front hotel was in the perfect location: Platis Gialos. Bus stop 2 min walk & 15 min direct into the old town of Mykonos. Lots of restaurants & shops within 2-5 min walk of the hotel. Got a car rental to go all over the island and still this hotel best location. The room & facilities were really good. The buffet breakfast was great, fresh with lots of variety, But hands down the staff were amazing. The 2 young service ladies at the buffet so friendly & attentive. A shout out to both Maria & Giselle at reception! These 2 absolutely lovely ladies welcomed us with open arms and treated us like family. So helpful with information, so kind. Thank you so much Maria & Giselle, you both are the reason I will return not only to Mykonos but to the Kosmoplaz Hotel. Unfortunately, we witnessed some guests who felt that they were self entitled & that rules don’t apply to them and treated staff poorly. The staff did not deserve to be treated this way. If you can’t be kind & respect rules go rent a private villa.

It was good, but it’s not any party around

Excellent location, not too close of the night life, But close enough to go and have fun the nights you want to. The syaff is very attentive to your needs and the room oversaw the bay. No hotel lazy chairs on the beach though, bit, went you consume in the restaurant they give you one for free for the day. Over all I will stay there on my next trip to Mykonos.
