Mario is a wonderful host and a great person to stay with in Mexico City. His apartment is very well located in Condesa. The accomodations are very basic where you may need to buy a couple things to make your stay more comfortable - it's good for a short period of time but for longer stays I would recommend looking for a more solid rental that matches up with market value of the area. But Mario helped with the check in process and was kind enought to refund me a couple days when my other accomodations adjusted the move in date.
