Very nicely renovated apartment, couldn't have asked for more. Quiet at night, great quality beds - made for good rest in between exploring Madrid. Ignacio also kindly let us check out late as had no in coming guest that day - thank you very much, we got another half day visiting Madrid before our flight out.
The location is walking distance to the main museums and shopping areas such as Puerta del Sol. A few streets away is Casa Patas for flamenco.
