Traveloka said there is a 24/7 reception desk (misleading info), but this is a self service homestay!!! Cozrum Homes sent information via Zalo and the guest opened the door themselves... went to the room and did everything themselves to open the lock box to get the door key (key) and the magnetic card (only used to open the door). Cozrum Homes asked when to check in. The answer was check in at 2 p.m.. About 2 hours later, we arrived... after getting inside and dragging the suitcase up to the 2nd floor (there is no elevator here). Opened the box... took the magnetic card, but there was no key (used to open the room door). Luckily the room was not locked. Entering the room... the bed was messy and the bathroom was dirty. Wtf... They haven't cleaned the room for the new guest yet! Going downstairs, I saw a new woman and I told her about the problem. She told me to go down here and "wait", I'll go clean the room right away. About 20 minutes later, I went to the room. I thought everything was fine but I was wrong! She said this room needs a key to enter and exit, I will give you the key. After trying several keys but none of them fit, she called someone and said she would bring the key. I had an appointment so my wife had to stay in the room to keep my things! After that, a guy came to remove the lock and take it to make a new card, but it couldn't be done and had to replace the lock!!! I planned to check out the next day but I was so tired of this place that I checked out that evening and rented another hotel. What a memorable experience ....
