My hosts were very nice and friendly. Even though I arrived after midnight, they were waiting for me and didn't even complain. I utterly enjoyed staying with them. The room was small, but very comfortable for a short stay and very clean. They have a cute dog named Cumba :-) The location of the flat is great. It took me less than 25 minutes to walk to the old district, around 15 to 20 minutes to the sea. It is about 10 minutes away from beautiful Montjuïc. Thanks, guys! Hope to see you in Berlin!
