I complain about 3 things: the bathroom smells bad even after it is cleaned, eventually smells bad again, the room was beside the elevator which was really noisy, specially at night, it was hard to sleep. And the key which is an electronic card i had to go all the time to reception so they could configure it because it stopped working all the time.
The good things are the location, you have a metro station in front of the hotel, and also the people who work there were amazing, very nice people
