This apartment is in the heart of Madrid - you are close to everything: great restaurants, historic places, convenience stores. The apartment is very comfortable and well appointed. Be ready to climb some stairs with your luggage.
Remember you are also in the middle of city noise - if you are a light sleeper, just bring a pair of earplugs, that will do the trick.
Gorgeous, spacious and impecable apartment right in Plaza Mayor, a great choice!
