The appartment was like Airbnb pictures. It was very clean and quiet. Wally was here at time. He shown us ( I was with my family) how to use everything in the flat. He also advised us the most important places to see. He was very nice. He was very reachable during our stay. We had everything we need in the flat especialy in the kichen. The area was very nice. We could buy all we needed. The subway was at about 3 minutes from the flat. It links too many famous places in the city. We were at about 6mn from Sants station where you can leave your luggage in big locker only for 5,20€.
We realy enjoyed our stay. I recomand this place. Thanks Wally.
