There were 6 of us staying in the apartment and it was perfect for our 3 day city break. Very close to the city center and the metro station, shops and restaurants close by; there is some noise coming from the street at night, but this is true for any apartment in the heart of Madrid. The apartment is not very large but the space is used wisely and it is clean and comfortable, including all necessary amenities. Alex was very prompt in communication and she also had some nice suggestions for our visit.
