Olivier and Arquimedes's place is just the best! The first day, Olivier managed to host us last minute. The house is beautiful, clean, comfortable and surrounded by tons of nice (and cheap) resturants, bar and cafes. Close to the underground and 10 minutes walk from el zocalo and the cathedral.
Arquimedes has recommended us many many cool places where to shop, eat, etc. He is always ready to answer all our questions!
Communication was great. Would stay here forever. :)
