We loved our stay in Madrid. Gloria and Dani were very responsive and the place truly had some of the best views. After long days of sight-seeing, our best look at Madrid was from the place were were staying.
The location is great and in close proximity to different pieces of Madrid we wanted to see, making it easy to get back for a quick shower or siesta. My only caution would be to guests with any mobility concerns -- the staircases, particularly the one up to the bedroom is (as shown in the photos) not accessible for everyone.
