The apartment was in a great location-we walked to most sites, or caught taxis( these were inexpensive) to things further away( eg park guell). We didn't actually meet Damien but found he was extremely responsive to all email correspondence. We met his assistant maria( ?) she was really helpful and was based in the foyer of the building so we were able to ask questions as required.
The apartment was spacious-I did have a problem with the loud street noise coming into the lounge/dining and the 2 front bed rooms. But appreciated the 3rd bedroom which had amazing black out blinds and was extremely quiet.
We loved Damian's recommendations for places to eat. We will be back. Barcelona is as wonderful as we remembered and is a great place to travel with small kids.
