My partner and I had a great stay in Mike's apartment. He was there to meet us on arrival, and showed us around the apartment. Everything was extremely clean, and well presented - exactly like the photos.
The bed was one of the most comfortable ones we've slept in whilst staying in a holiday let, with really nice linen. The built in speaker system for your iPod was also a great touch.
The location was perfect - about 15 minutes to Las Ramblas, and just over 30 minutes to beach. But if you don't feel like going too far, there are some really excellent bars and restaurants on the same street as the apartment.
Will definitely be staying there next time we visit Barcelona.
