The best Airbnb hosting ever, Fernando is a Pro! I love the area, slightly tucked away from the tourist hassle of Rambla (15 min walk), in the middle of tons of up'n'coming small restaurants....a much better Barcelona experience!
The apartment itself was clean, comfortable (good, quiet A/C), fitting for a solo traveler or a couple (1 queen bed + 2 small beds). There's a full kitchen, with cooking essentials. Plus a good washer & ironing board. The Wifi is unfortunately a bit slow.
The apartment really does not have any windows other than the kitchen one that is facing the patio - and directly another neighbour's patio. That was however completely fine for us.
