Ricardo is an excellent host, helpful and very obliging. Listening to music of his great collection we had some really inspiring conversations (e.g. about mexican wrestling, fine arts, british Indie-Rock-Bands or mesoamerican cultures). Several times a day he delighted me with his perfect italian-style espresso.
Close to Bellas Artes the apartment is situated in walkable distance to the centre and to several metro-stations, therefore it's perfect to reach every part of the city easily.
I had a really comfortable stay there.
A highly recommendable place!
