Anna was a good host, easy to communicate with. She responded quickly to our messages. We were greeted by her father at the apartment, who spoke little English but it was not a problem (Anna was easily reachable, I speak a little Spanish, and we used google translate). He even recommended a luggage storage place for us to leave our bags after check out.
The pictures are accurate and the flat is spacious, clean and very well equipped (kitchenware, iron, hair dryer, straightener). The only issue we had was we ran out of hot water for the shower.
The flat is close to two metro stations and well located near a touristy area. The street itself is a little more sketchy but we didn't have any problems. There is a bar downstairs though, so one of the rooms is a little noisy meaning you can't open the window, but there is aircon.
