Angel was such a great host. To stay at his place was very good. He arranged breakfast every day very promptly. We were able to attend the MWC and have a good time at Barcelona. The location is very central and everything is walkable and Angel provided public transport ticket which also was very helpful. We would definitely stay at Angel's place when we come back to Barcelona next time.
Only advice is to keep your things careful because Barcelona is not very safe and we lost some of our valuables.
