Cesc was an amazing host. He was there waiting for us when we arrived and explained everything about the apartment and areas to visit. His apartment is very nice.
Pros, About 6 blocks to Sagrada Familia and about 15 to 20 minutes walking to the rest of the must sees of Barcelona. Clean apartment and helpful host. Close to bars and restaurants.
Cons, Very tiny shower. 2nd floor no elevator which really means 3rd floor. Staircase need paint which causes a bad first impression. Once you get to apartment you will be fine.
Tips: I would encourage you to take the Double Decker bus At sagrada Familia and you will not be disappointed, it takes you to all the must sees for just 30 euros.
Overall good stay.
