I spent one night at Olivier& Arquimedes's place, The house is exactly as shown in the pictures with very nice terrace, the bed is very comfy and the room is spacious. The location is just perfect , in the heart of the historical center of Mexico city and without to mention how Olivier was accommodating, he accepted to host me very early on a Saturday morning ( I really appreciate).
Olivier is also a great human being, helpful and very friendly . I highly recommend his place . I will absolutely stay in his house next time.
