Excellent location, very well maintained but small apartment (especially with 4-5 people including kids).. all amenities are good and you will enjoy all main attractions at walking distance away. Internet is very good, All TVs are smart and equipped with Netflix. The Madrid tour bus is right across the street and all other areas around the apartment are worth a visit (retiro, prada etc.). the location itself will save you hassles of moving around in taxis and busses - just walk on.
