The apartment is spectacular, it is the best area in the center of Madrid, completely exterior and with 4 very spacious and pleasant bedrooms, balconies throughout the apartment. The price-quality ratio is really good. I recommend it to everyone. You are 2 minutes from the Royal Palace.
The street is very quiet to rest despite being in the middle of Madrid de Los Austrias. My family and I have been very happy and I recommend your stay.
