Flat is close to the subway station and to a few bus stops which makes it fairly easy to get to the busier parts of Barcelona. Check-in was straightforward with clear instructions provided by Roger. You have to walk 10 minutes to get to the Rambla of Poblenou where you find eateries galore.
Unfortunately, some of the neighbours living in the same building were quite noisy, so much so that our kids would wake up from it at night. The balcony door is also very poorly insulated so that the cold and noise from outside gets in somewhat unhindered. There were refuse trucks of some kind emptying containers literally around midnight and it sounded as if they were inside the building.
Overall an okay option if you don't mind noise.
