Laia responded quickly to my messages which I appreciated. She sent the keys by post but they didn't arrive on time which was a bit stressful for me but she arranged her nephew to check us in and he was there right on time. The location is perfect - not very far from la Sagrada familia, the Gothic quarter and the beach, and there are plenty of restaurants, supermarkets and bakeries around. The building is also nice and there are two elevators so it is easy to reach the 7th floor. The apartment is nicely furnished and it is convenient for up to 4 people. The only inconveniences were that the bathroom is quite small and there were no soap neither shampoo and we also had to buy toilet paper and garbage bags. I totally recommend this apartment for a stay in Barcelona.
