The apartment was nicely furnished and conveniently located very close to a metro stop and near the Camp Neu football stadium. It was for the most part very clean, except for some mould on the wall in one room. Overall, it fit our needs as a group of students needing a place to stay for a visit to Barcelona.
I had some difficulty arranging the key pick-up when I first booked the apartment. The rental appears to be through a third party company that requested I fill out an "arrival form," however, there were technical issues with the online form the prevented me from completely it. Eventually, I got in touch with David, who was our host (we never met or heard from Pilar, the host on the airbnb listing). Once we got in contact with David, we arranged for him to meet us at the apartment when we arrived to let us in. We appreciated that he was flexible with us when our flight was delayed and we arrived about an hour later than planned. However, the apartment was not quite ready when we arrived; it was still being cleaned.
The other issue we experienced was that upon arrival, our host, David, requested that we pay a Barcelona tourism tax. The tax worked out to about 30 euros (for five of us staying three nights) and he wanted us to pay it to him on the spot in cash. We were slightly taken aback, as we had already paid for the airbnb, and did not expect any further expenses.
