We never met Maria and Mario, but Sandra and Ines were our main point of contact during check-in and our stay and they were extremely helpful and kind. They took the time to give us recommendations, made sure everything was okay during our stay, and kindly provided us a bowl of fresh fruits. The apartment itself was centrally located, in the heart of Barrio Alto (restaurants, bars, etc.) but the apartment faces the courtyard so you can't hear the hustle and bustle of the streets. The apartment was clean and stylish, exactly as pictured in the photos. Would not hesitate to stay here again.
