Great place for a short stay. We rented the suite for 4 adults and it did feel a little crowded, but it was fine for just 3 nights. The rooms and bathroom were clean and there were plenty of towels. Each room had its own door which was really appreciated. It's worth noting that the bathroom did have a door, as well. I know some of the reviews have said the double rooms don't have one, but the suites do apparently. In case anyone else is worried about it, like I was.
Note that there's no elevator and the stairs are steep. We all had small carry-on luggage and were barely able to fit in the stairway, so if you'll be traveling with medium to large luggage it'll be nearly impossible to get up the stairs.
It's pretty much a self check-in. You'll receive a link through whatsapp to pay the city tax before you arrive and then you'll get the codes to enter the hotel and your room. I know they also have luggage storage in the basement, but we didn't end up using it.
Also, the area is fine. Subway stations close, places to eat nearby, feels safe walking around the area, etc.
