I visited BCN in August 2021 together with ny husband and 2 kids, toddler and baby. The neighbourhood is great, one of the best locations of Barcelona, great restaurants, Turo Park closeby, very nice stores.
However, the apartment itself is not a 5 star apartment and is not for exigent guests. It is important to say that windows are interior, meaning no window will overlook the street. There is no view of Barcelona. The furniture is rather old and modest, but it is well equipped and not really missing anything (at least for a family with small kids). Apartment could be cleaner, for a family with babies. Dishwasher was broken when we arrived, but they quickly sent someone and fixed it the following day.
Communjcation was great at all times, hosts very helpful and receptive.
