I’ve been living in Javier’s house for one week.
The room was as described and the bathroom inside was a great advantage!
The house is within walking distance to the major tourist attractions; supermarkets are near the house and also buses and the tube if you have to go elsewhere (Beach, Camp Nou, Airport El Prat).
Javier and his son are very nice people, I felt like at home!
I recommend Javier house for everyone needs an accommodation in Barcelona.
