The location is great and very close to Gran Via. Easy access from the airport. Nice neighbourhood with bars,restaurants, supermarket etc. Almost next to the apartment there is a locker shop in case you want to leave your luggage if you are leaving late for the airport and you need to check out.
It was very nice to have coffee machine with coffee and sugar, fresh fruits and beers as a welcome. There were all the amenities provided in the bathroom (shampoo, wash gel, toothpast, body lotion, hair dryer, iron).
The space is small but if you are all day around in Madrid, it is just the perfect place to stay.
