Wonderful apartment and hosts!
There are two metro stops within a few blocks of the apartment. Additionally the location is only 10 mins on foot or one metro (tube) stop from Barcelona Sants train station.
The apartment has A/C in the communal area and fans in the bedroom, making the stay delightfully pleasant even in the 30+ degree heat this August!
Lastly, but by no means least, the hosts kindly allowed luggage to be left in the communal area after check-out for same day collection so my partner and I could make the most of our last day and visit Park Güell without worrying about what to do with our suitcases!
Great Airbnb, would recommend!
