What a beautiful flat! It is so gorgeous and clean, it looked like a fancy hotel room with extra amenities (towel warmer? bath tub with jets? Helloo! Fancy!) It could not have been in a better location for exploring Madrid. It was a 5 minute walk to all the big sites. The windows are on three sides of the building, which is great for ventilation. At night, since you are in the heart of everything, it can be noisy but once we closed the windows and turned on the AC unit I couldn't hear anything outside. It was so lovely to enjoy a glass of wine at night as everyone was going out and tea in the morning as everything was opening up again.
