We stayed a week at Rosa’s place and very much enjoyed it. It has great access to services (grocery, transportation, food, et all) and is a bit farther away from all the tourist noise. People greeted each other on the street often — if that gives you an idea. The place was very clean and the amenities were in quality shape. If you want to be in a more local than tourist area (15 min walk to S. Marcos) then this is a great place — would recommend.
