Alba took over charge of the apartment before we went (we had booked with Airbnb and another guy was in charge) and the transition was seamless.
Communication was faultless.
Alba met us on arrival and showed us around the (beautiful) apartment. The view outside was even better than in the pictures. She had some tourist information leaflets and recommended some places to eat and places to see. All of it very useful. I have no faults to mention... Only thing is... There are lots of stairs going up to the apartment from the ground floor and no lift... So anybody with health problems or using a wheelchair this is obviously not ideal.
I would have no problem booking here again should I ever visit Barcelona again!!
