The flat is well located near most attractions and is easily walkable or via the metro. The location is the only plus I would give it and other only reason for staying there. The room (no.3) is small/tight (once luggages are in there). the door had no curtains, so you could not get change in there. The bathrooms (both of them) are small and tight. The one I used (closest to room 3) had a slow shower drain which overflowed when you shower. I travelled on my own, but two in the double bed would be tight. The bed squeaks when you turn and the walls are paper thin. The kitchen area was bare, with no milk or coffee/tea. I would not describe the apartment as 'big'. If you just need a place that is conveniently located in Barcelona to sleep & wash it will do the job. The price was not cheap, but fair given the locations.
