This is a superb apartment in an unbeatable location.
It's in Malasana which has an abundance of brilliant bars and restaurants and it's a short walk to metro stops and Grand Via. A well-stocked Carrefour Express is at the bottom of the street, and there are also good coffee shops and bakeries nearby.
It's a hefty walk up the stairs to the apartment but worth it because despite its brilliant location, you get no street noise at night. Wifi is also good and the shower is excellent.
Jose's communication was prompt and helpful. Highly recommended for a great trip to Madrid.
