The apartment is very well located, in a beautiful neighborhood, very close to restaurants, bars and the center of Madrid. There is a reception open almost 24/7 with very friendly personnel to welcome the guests and help them out.
Our apartment was very cosy with a beautiful terrace, everything was clean and in order.
We highly recommend it if you want to enjoy your stay and live Madrid's atmosphere in a cool place (just a tip: if you are two couples just check if there are two separate bedrooms in the apartment though!)
