The description is 100% correct, the apartment is very comfortable and located in a really quiet neighbourhood, despite the proximity of the metro station (a couple of blocks away). You can get to the beach (a better, cleaner part of it) in about 10-15 minutes walking. The nearest supermarket is around 5 minutes away, and it sells everything one might need.

Flor met us on arrival, she was very friendly and helpful, so we felt we were being treated very well.
The apartment itself is quite spacious, it was perfect for the four of us - we all were very happy with it, and are going to recommend it to our friends!
The only shortcoming that comes to mind was the lack of the elevator and the narrow stairs you need to use to come up with your luggage, but that's something you only need to do once, so not a real problem.
