I wouldn't describe this as a luxurious apartment - although it has a few decorative touches the bedrooms and furniture are quite basic, there was limited glassware and we ran out of toilet paper.
Having said that, this isn't a negative review. The apartment is in a great location, it had been thoroughly cleaned and the beds and sofas were comfortable. It suited out needs, was reasonably priced and we'd happily stay again.
There are several supermarkets within a few blocks, the closest local general store is only a few doors down and there's a great cocktail bar (Tandem Bar) one block up.
If you're coming from the airport the A1 and A2 airport buses stop at Universitat (3 1/2 blocks from the apartment) on the way to Plaça de Catalunya, but not on the way back to the airport. The fare is €5.90 single or €10.20 return payable on bus or by buying ticket in advance. Buses run every 10 minutes and take about 30 minutes.
