We have a very pleasant stay at Luca's place. It is exactly the same as described and can access the underground and supermarket within 1 min walk. Actually just right down the street. Super convenient.

FYI, since we book the whole apartment, we cannot keep our luggage in the house after check out time (10a.m.) luckily there is luggage kept place at the Sants train station and you can actually take the train using T10 to airport, so it is not a problem at all.

The only pity thing is we spent our new year eve in barcelona and the place is so close to where firework held but when we ask Luca if there is any special event for the new year, we are not told for this. Otherwise we must went to see the firework!!
