I really enjoyed my stay at Vicens place. It was very cozy and comfortable, while affordable. I had a beautiful little room plus bathroom and balcony for myself. It was very clean and there was everything i needed, also Vicen is a really nice lady and always there for answering questions. The Airbnb is not in the Center but there is a metrostation nearby and you just have to drive two Stations.
All in all i really can recommend this place!
