I stayed 7days in Sebastian's house and It was ABSOLUTELY GREAT!!! He's house is awesome as same as the pictures. It's super clean and well maintained. Also Sebastian is so nice in everytime. Even though we had little language barrier but he's great attitude and kindness made everything good. Even when I went to airport to came back to my home, He gave me a ride!!!! I never expected the ride so it was super surprising. And the location is also great. It takes only 5mins to metro station the Placa de sants which is line 1 and line 5 stop. And there are lots of bakeries for breakfasts and lots of markets and restaurants.
I fell in love with Barcelona and the one of reasons is Sebastian's house.
