Everything was ok, as we expected. The apartment was clean, perfect location close to the Ramblas. Maybe a little small for 9 people, I think it's perfect for 6-7 persons. Hernan was very friendly and helpfull, he also arranged a bus to pick us up at the airport and bring us back. There's a lot of noise because in the apartment of the traffic; we didn't mind at all but if you're looking for a very quit place it's not here.
I would definitely contact Hernan again if I go to Barcelona again!
