Very clean, comfortable and simple apartment in one of the most posh neighborhoods in Madrid, kind of like the Upper East Side in NYC, but central enough to easily walk to other places and close to the airport. The park is across the street which is nice, and the traffic noise is blocked by a double set of doors. I slept very well because the bedroom is completely blacked out. I was mostly walking around during the day and also used the apartment to work... there was some construction noise during the day in the living room but that's normal for Madrid and the bedroom itself was INCREDIBLY quiet. Also the Leeways rep was very sweet!
