Francesco's place is a great option in Barcelona. It is in a good location - pretty much walking distance to most places and not far from the tube. There are also some delicious local Pinxos places close by.
Check-in was really easy, and Monica had heaps of local knowledge and recommendations for us.
I would say, that whilst the apartment is clean and well-presented, it is a little smaller than it looks in the photographs. And the single beds really are quite small!
I would definitely recommend this place for a couple or family spending a few days in the city.
