Amazing apartment and great host Magui! Roof terrace/balcony is very cool to drink, to eat, to relax. A whole historic apartment is very convenient and quiet, a big kitchen with all you need. We liked this place very much. Location is very good, 5-10 minutes walk to most interesting places, plazas, the palace and metro. 20 minutes taxi ride to the airport, public transportation is good as well.
The only problem is the Madrid local government which trashed most of Plaza Mayor with some ugly structures and construction running, most of Plaza is closed for visitors. Unfortunately this is a global problem - stupids in power ruining nice historic places, not created by them. That's sad... But you always can avoid looking down from terrace - look around - it's really cool, beautiful and unique - I would stay there again! Highly recommended!
