The apartment is very conveniently located near the Plaza Mayor, the heart of Central Madrid. Even though the area is busy with tourists and restaurants, quite noisy at night actually, the apartment is quiet, protected by double glass windows. It is located on the first floor of a building, but this floor has an independent entry, with little risk of having unwelcome visitors. It was very clean, well equipped. Our stay took place during a cold and rainy week, but the heating system was working with satisfaction. Our host was quickly responsive and helpful.
It is an excellent place for a couple visiting the centre of Madrid and the Museums. Subways and trains stations are nearby, which allowed us to visit the Escorial and Toledo without too much hassle. In any case taxis and Uber cars are available and cheap.
