Great experience, overall.
Pros: comfortable room; clean; great location; secure; adequate breakfast, with spacious dining area; outlet accommodating both plug types C and B.
Cons: Tiny shower; unusual elevator; lots of noise; possible lack of communication.
For the cons, the noise was largely from the elevator (which has a warning alarm when it's not closed properly, due to its weird door system) and what seemed like constant housekeeping (a mild complaint, as I did like the hotel's cleanliness). The one time I needed to talk to a concierge, he didn't speak English, so that may be an issue.
The shower is the biggest detriment. It is incredibly small and, thus, hard to maneuver in. The large, billowy shower curtain eats up some of that space as well. Needless to say, showers were a bit uncomfortable. It is certainly not a shower/bath combo as advertised on this site.
In that regard, despite the picture, there also is not a kitchen in the room.
The hotel has many positives. It is near many attractions (like Obelisco) and bus stops for the tourist. It is also near multiple local restaurants--a good one right next, for example, or the ice cream place across the street. The hotel is clean and well kept. The front door is securely controlled by the concierge, and the outside door within the room also locks. The room itself was very well maintained, and the housekeeper took great care with anything left strewn about.
Despite the elevator and the shower, it was a great stay!
