We had a wonderful stay at Casa Veganto.
The location is excellent - you walk out of the building, and literally 10 meteres away is the Metro station. The hosts were amazing - really friendly and helpful. The room was very clean and we had our room done and cleaned every day!! There was a complementary breakfast, which was really tasty. In the afternoons they have "vermut o'clock" which is the time to meet up with other guest and have a glass of wine, cava, or beer. I would highly recommend this place and for sure I'll stay here again in future visits to Barcelona :)
