We had a very pleasant stay in Madrid. Julio's room was perfectly located, in the heart of the city. Everything can be visited by foot, which we did during our visit. The room is simple, but very comfortable and clean. Air Conditioning and bathroom (shower and toilet) was at our disposal in the room which is a big plus. Julio is a very discreet but nice host and we felt at ease sharing a room in his flat. The only minor remark I have is about the door separating our room from the other parts of the flat : it is very thin and not very noise-cancelling which can be a problem if you are a sensitive sleeper like me.
