Whilst very small the accommodation satisfied our needs. It was lovely and qiuet except when a neighbour had visitors but was never an issue at night. The flat was fine and the only thing we would have changed is the lighting. There are lots of lamps around the flat but it actually doesn't get much natural light.
If that doesn't bother you then I would recommend this place and would definitely consider booking again when we next visit Barcelona.
We stayed for 4 nights but didn't realise until the last night that there is a large street full of resteraunts - only 5 mins walk away! The street is called Carrer De Blai. It's brilliant.
