Well, first, the room: every hotel I have visited has AC and heating. Unfortunately, this brand doesn't have those services. We have to leave the balcony door open all day to keep the air cool. Also, my neighbor on the side of our room smokes a lot. We have to choose: leave the door open and smell the cigarette smoke all day, or close the door and suffer the room heat. I have requested assistance from the hotel, but they don't have any way to help.
Regarding the second point, the room service isn't good; the food is always the same. The breakfast menu is two plates only and never changes. Dinner is the same, only one menu plate, disgusting, all amenities need an update
On the other hand, the staff are very professional.
