Location is fantastic , couldn't find better! You open your window and you see Sagrada Familia.. downstairs by every 5 meters you see brunch places and restaurants and you just cross the street and you are in the metro !
Host was really responsive ! We had a problem with the AC (it happens) and the host reacted quick by sending a technician and heaters and blankets!
What he can do to improve is refresh the AirBnB with a paint job probably and replacement of the windows !
Overally really thankfull we found this host and AirBnB ! Had a great vacation in Barcelona!
