Great place to stay rather at the North-western end of the city center. However, everything of the important tourist areas is easily to be reached in walking distance.
Cool bars/restaurants for a typical Spanish breakfast or Tapas among locals directly around the corner (e.g. El Sardinero or Palo Santo).
The apartment itself is located on the 2nd floor (no elevator) with a nice private rooftop terrace. Looks exactly as on the pictures and we enjoyed the stay overall!
Unfortunately the kitchen (i.e. cuttlery and glasses) and the bathroom (i.e. soap dispenser and toilet seat) were not really clean. Also the wifi did not work properly and if, only with weak signal.
