Rosa's mom welcomed us upon arrival. She spoke only spanish but we managed ! She showed us maps of the neighborhood and of barcelona, and explained how everything worked.
Lots of heaters everywhere around the house, that came useful because it was kind of cold at this time of year !
Really close to the sea and the Poblenou Rambla to go out and eat, AND close to the Barcelona Subway.
The bed was pretty comfy (also we didn't try the one in the second bedroom) and there was everything we could have needed.

Only note to add is that the neighbors were a bit noisy when we arrived but seeing as it was in the early afternoon, it stopped before we went to bed and we had no noise during the night. (But the walls are a bit thin during the day!).

Thank you for everything ! It really was a great vacation :)
