This is a great place in a wonderful location, accessible to all the major places you would like to visit in Barcelona, very centrally located.
One caution, this is really a 1 and 1/2 bath as the shower in the small bathroom is about 24 inches by 24 inches with a shower curtain on two sides, really not a usable shower. We have used many airbnb homes in Europe and this is smallest shower we have seen. Also, the small bedroom has space enough for the bed only, just so you don't have wrong expectations.
Otherwise, this is a great place. The host was very responsive and communicated well. The check-in process was easy and Dani did a great job in explaining everything.
