this was easily the worst experience we've ever had with an Airbnb property, despite the fact that we loved Barcelona and enjoyed our visit to the city. The host was not particularly helpful, but the real problem was the apartment - it leaked water onto the floor for 3 days, when finally stopped, there was a strong mildew smell, both my wife and daughter have allergies and were sick as a result. The fridge was not clean, and under the sink, the garbage pail stunk. One night, there was a loud party next door, and the smell of vomit permeated the hall and lift for the rest of our time. The tiles were loose throughout the apartment, the heat was impossible to control. The owner gave us a 10% refund. If it had been a hotel, we would have left obviously, and stayed somewhere else. The next place we stayed at in Seville was the exact opposite, a wonderful experience, a fantastic place, and actually a slightly lower price. We're not complainers by nature, but this was a brutally bad experience, and the pictures don't tell the story.
