Javier's place is really fabulous. Excellent location literally five minutes from the Prado and near tons of restaurants and coffee shops. Super duper clean and with all the major amenities. We did have some trouble getting the door open - it requires pulling it toward you as you turn the key - but once we figured that out with the help of the neighbors, it wasn't too difficult. We didn't meet Javier, but he was extremely quick with responses throughout and always answered any questions we had. Would stay again.
