I had a nice stay at Ricardo's place. The house is very clean and spacious. I especially liked the office area with a wide desk, as I spent most of my time working there. The wifi worked pretty well during the day, it did slow down a few times but generally hovered around 7-10 mbps. The location is quite convenient, you're very close to a metro stop and located in Escandon, a neighborhood adjacent to La Condesa but has virtually no tourists. The area is quite safe and has just about everything you could need within walking distance. Ricardo's place is a bargain, I'd stay again.
