Wonderful apartment in the heart of Madrid. When we arrived, Marga's assistant Daniel was waiting for us to show us the apartment and provide keys. The location could not have been better; walking distance to shops, restaurants and trains.
The apartment is on the 3rd floor, but there is a small lift which was convenient while traveling with luggage. The apartment is a corner unit with balconies outside every window. It was beautifully decorated and the bed was very comfortable, albeit it bit small.
The only negative, which others have mentioned is the noise at night. We were there for a weekend and Friday and Saturday nights the noise from people the street is very loud, until about 6am. Marga does provide earplugs, but we found headphones with white noise necessary. So long as you know going into it that it will be loud, I promise you will love this apartment and it's location. Marga and Daniel were wonderful hosts.
