Mike was a great host. He left us Barcelona guide books and offered great advice. He even helped us book a taxi to the airport on the way back. The apartment was designed with a great use of space and was very comfortable, although (being 4 months pregnant) the 3.5 flights of stairs left me seriously out of breath. The neighborhood was great with a non-touristy feel and just a few minutes walk to two different metro lines, making it easy to get around the city.
