I recommend this place. The pictures are accurate, the room is quiet and clean, and the mattress is comfortable. I would stay there again.
Pedro likes to be petted.
Maria is easy-going and available if you have questions.
There are several places to eat within a block or two, and one of them is next door to the building.
There's a Metro (subway) station a few blocks away. You can walk there in 15 minutes or so, and it's the easiest way to get around the city.
