Wow, this was a fantastic apartment. I can't recommend it enough. Fantastic location (very walkable to the city centre), and a fantastic place to stay in. Very clean; well-furnished; very comfortable beds. Well-equipped kitchen, spacious living room and area to relax on sofas with the TV. There were 6 of us staying so having two bathrooms was very useful. Carmen was a lovely host, very kind and she took the time to show us around everything in the apartment, even booking a taxi for our return. One of my very best Airbnb experiences so far, you should definitely stay here if you are in a group visiting Madrid.
