The apartment is all-around great. It is a beautiful and modern space with all the comforts you could ask for. It even has a washer/dryer which I had no even heard of before.

The location is unbeatable. It is one block North of Gran Via and walking distance from Plaza de Espana, Callao, and even Sol. Despite its central location, it is still very quiet at night.

A word of caution: the bathroom is curiously located in the middle of the apartment and is not really insulated. Because of this I would not recommend it unless you are very comfortable with your traveling companion(s).
