Thomas' apartment in El Born was fantastic for our four day stay in Barcelona. It is in a fantastic location in what seemed like the best part of Barcelona - great bars and restaurants and shopping just at the doorstep.
The stairs were hilarious - but not for the faint hearted. If you can manage these, then this apartment is definitely worth staying in. Sadly the weather was not good enough for us to fully enjoy the rooftop terrace. Maybe next time!
