Rocio's flat is an a beautiful location, La Condesa is a leafy suburb close to the centre but away from the busy, crowded parts. After a long day sightseeing it's lovely to come back to a peaceful flat. The flat itself had everything we needed. The beds are really high quality as are the general furnishings around the flat, which were all chosen with really good taste. I really have nothing negative to say about the apartment, it's as described in the listing and the photos give an accurate impression of how nice it is.
I didn't meet Rocio herself but she was very pleasant with her quick replies to our questions, we were never left waiting for a response. Staying with my parents-in-law meant we had a few more questions than we possibly normally would have had, and Rocio was very amenable with what we asked and this made our stay much nicer.
There is a supermarket within about three minutes walk, plenty of small bars and restaurants and a good variety of street food if you want something quick and cheap.
I'd highly recommend staying at Rocio's flat.
