Mercedes was the perfect hostess. She made us feel exceptionally welcome, gave us lots of great advice and recommendations, and was a great ambassador for Barcelona.
Her apartment is in an excellent location, with a fantastic view over the square, and easy to get to from the airport using public transport. The breakfast spread was very welcome, with very good coffee from her little machine, and she even gave us a drink in the evening.
Plenty of bars and cafes on the doorstep, just off La Ramblas.
