Our stay at Barbara's was definitely a highlight of our family's 3 week trip to Europe. My wife and I were travelling with our 3 month old and this place was absolutely perfect for the 3 of us. The location is perfect; a bit outside of the craziness of the tourist centres (La Rambla/Gothic) so had a much more laid back feel to the neighborhood.
Barbara was extremely accommodating and made sure everything was set up and comfortable for us upon arrival. Tons great restaurants within a couple blocks (including a great Taiwanese spot right downstairs). The terrace on the back and small balconies on the bedrooms facing the street were incredible. We could have stayed there forever (and did spend a few too many hours daydreaming about how we may make the move).
The kitchen, bathroom, and living spaces were in fantastic shape. The grocery store is less than a block away too. Would wake up and walk with my son at 6am and always felt safe and welcome in the area of her apartment.
