We book the flat as we know the area, and was exactly what we were looking for in an extended break over New Year.
The place was easy to find, met the manager Alex, who was friendly, informative, and helpful. The flat was spotlessly clean, the beds comfortable, and most importantly, relatively quiet for such a densely packed place as the Gothic quarter. There are plenty of bars, restaurants nearby, as are convenience supermarkets. It was a pleasure to stay there, with the manager just a call away if there were any problems, which there weren't. I'd highly recommend this flat, and will definitely consider rebooking again should we return to Barcelona.
