The apartment was just as advertised, very clean with modern amenities. Sergio was extremely helpful checking me in and offered great information on restaurants and local sightseeing. The location is very convenient, close to a subway stop and walkable to restaurants and other points of interest. There's a small grocery store on the ground floor of the apartment building. It's a short walk up the hill to the castle. The only downside was that the square next to the apartment was loud at night, sometimes with arguments and other conflicts. It didn't affect my stay, but I might have been wary about going out late if I wanted to sample the nightlife.
I would recommend this apartment.
