We have just had a fabulous 4 nights in Xavi's apartment. He is a great host, very helpful and communication was excellent. The location is great and made getting around Barcelona easy. Plenty of local bars, coffee shops, restaurants and cocktail bars. 20 minute walk to Las Ramblas. Easy journey from the airport, either by public bus with 1 change or the Aerobus.
We would definitely recommend Xavi's apartment
