I have lived in Barcelona and I chose this place based on LOCATION vs PRICE.
Poble Nou where Pau's Place is location is the best place to live and stay in Barcelona, the Poble Nou Ramble is 2min away and full of bars and coffee shops and 5 min walking from the beach and 15 from the Port Olympic.
Pau's house is really stylish, and he is really polite, the beds are comfortable too and everything is really clean. It offers a small kitchen, but we prefered to go and eat and have coffe on 1 of the dozens of options around his place.
When I come back to Barcelona, I will try to stay in his place again.
