We had a great stay at Virginie's cosy flat. Some of the reviews mention the street being noisy at night but we didn't even notice and our sleep was never interrupted. The flat location is great. Just far enough from La Rambla so you don't feel in he thick of the tourist trap but can easily walk there in 10mins. The flat is also a close walk to Poble Sec which has amazing evening tapas and drinks for great prices. The only negative point was that the flat can get quite hot and there isn't a fan or aircon. But this was during June peak summer temperatures so not an issue at most times of the year.
