Communication with Koni was excellent and information was accurate. The apartment was clean and everything needed for the visit was provided including a map for Barcelona with various points highlighted. The location was central to Placa de Catalunya (less than 5 minutes for the apartment) and close to metro station and grocery store. The provided map had information on places to visit and how long it would take to get there by walking (radius of 15 or 30 minutes from Placa de Catalunya) which was what we did.
