Our stay in Barcelona was fantastic, in a big way due to the location of the flat - it is just few minutes from the Park of Ciutadella (great for runners), and very close to the rest of the attractions that Barcelona offers - we didn't even have to take any public transport during our week-long stay. The flat itself is very adequate for a short stay and Roberto, who greeted us and waved us good bye on behalf of Sonia is a really nice guy - we even got a welcome bottle Cava :)
And the internet connection was great and reliable.

Thank you Roberto and Sonia :)
