I stayed at Oriol's place with a group of friends for a week.
The apartment was quiet, clean and well furinshed.
It is not too far from the underground station and near to the bus stop. Moreover it is close to several pubs, supermarkets and restaurants.
The host has been really polte and quick to answer to our requests in the best way possible.
I absolutely recommend his apartment if you are looking for an affordable place to spend a few days in.
