Juan was very hospitable and friendly. He provided us with all necessary information and helped us with transport from El Prat airport. Transport from airport to the flat was really easy. The nearest metro station is Clot and the nearest train station is Clot - Aragó. Also we could left our luggage at his flat after check out. He also knows some czech words so I reccomend his place for czech visitors. (Velmi rád by poznal nějaké další cestovatele z České Republiky :) )
Juan, muchas gracias!
