We stayed in Barcelona during 5 days / 4 nights. The place that Angel actually recommended to us was perfect. Both in terms of location (in the very hip and happening Eixample neighbourhood) and in terms of space. 2 comfortable bedrooms and bathrooms, a nice and spacy living room and 2 cute balconies from which you can see Barcelona life go by.
Angel has been very response and helpful.
I would definitely recommend this apartment!
