I had a really nice stay at Fede's place. The apartment is in an ideal location, a very short walk to Plaza de la Merced and close to the historic center. You've got restaurants, bars and supermarkets nearby. The apartment was clean and had everything needed for a short stay. It is on the street level but noise was never a concern. Fede met me at the apartment to give me the keys for check-in. Check-out was easy too.
