Oscar was great with communication throughout our trip, and was there at the apartment to show us around. Unfortunately when we got there there was no power in the building so we were unable to use the lift (up 6 floors). Oscar was great about it and assured us the power would come back on later that afternoon - which it did.
The apartment was as the pictures suggest and there was a great terrace - nice de a beer in the warm evening.
The location was fantastic. After traveling around Europe we were looking to stay somewhere in Barcelona that is a little out if the way, more culture and less tourists. Gracia is certainly the place. It's about 400 meters (a few blocks) to the underground. The area was great, lots of cafés restaurants etc within a 5-10 min walk.
Oscar even arranged a return ride to the airport at the end of the trip. Only issues were the lack of power when we arrived (which sorted itself out) all in all highly recommended.
