Sergio is a very friendly and helpful host. He gave us a lot of maps and informations about barcelona and specially poblenou and you can call him if you have questions.
Poblenou is a very nice area with a lot of cafés and shops and also natural. The street is near the rambla del poblenou, it's some kind of the pedestrian area of poblenou and leads (as well as the carrer de roc boronat) to a beautiful beach in 5 minutes.
The appartment was nice and you can have a view in the court with its creative studio and orange tree.
