The property was a convent until a few years ago and has been entirely renovated within limits set by the city. For example, there is no elevator because one would not fit the building's historic character. The exterior is modest, but the interior courtyard is beautiful, and there is a roof deck with views of the city. To the management, I'd suggest some tables and chairs up there because it is such a pleasant place to sit.
The staff was friendly, helpful, available at all times, and spoke fluent English. There is a very nice restaurant on the grounds (El Particular) that is open 8-5 approximately.
My room was spacious with a cool tile floor and A/C, functional but not opulent. It overlooked the street but was very quiet at night. Calle Belen is one-way with limited traffic, and it really empties after dark.
The crowds and activity of the central plazas are a 10-minute walk. The immediate neighborhood feels a bit frayed with graffiti and a few deteriorating buildings. The sidewalks are rough. I walked every night until 9PM and never felt unsafe, but normal urban precautions are in order.
