I was visited Barcelona because of cultural occasion,mostly of Gaudi's art,architecture,mosaics.There is near the famous Sagrada Familia and the modern Jean Nouvel building Torre Agbar.In the park opposit the building where the flat/room is there you can sit,walk or having a cigarette if you are a smoker,as I'm.In the flat there are more rooms(3)with other guests too,so U are not alone.You can't close your room when you leave to visit the city.Arriveing is flexible.
