We had a wonderful time at Aleix & Alba Airbnb...
The place is perfectly located! It's calm and less touristic but still has all you need and it's especially really close to the metro.
The apartment is lovely and even though it was in the hot weather season, the air con. was keeping the apartment at perfect temperature.
Aleix was promt to reply or advise us for everything.
For all those reason, I'd recommend this place for anyone visiting Barcelona!
Thanks again guys :-)
