We had the best stay with Airbnb in this apt from EN VILLE! The flat looks damn STYLISH and is 400% clean, but still enjoyable with small kids (6,4). Although our kids didn't touch the decoration, I put some things away, so they did not break them. It is very convenient that the metro station and the bus station is very close and that the apt is located close to a very cool and stylish area (Parlament street). Keeping in mind that you are in Spain/barcelona it is quite calm, although I was hearing at night some peeps, but I think that is absolutely normal when you want to live in the city.
Edu is a very nice and polite host who made our stay just perfect!
I don't want to live anyplace else anymore and want to switch my home now to this flat ;-)
Thank you Edu we will come again!
