Unfortunately, our stay was the worst experience we've ever had with Airbnb.
1) Electronic key: to enter the apartment, they give you an electronic key that works with an app on your phone. That requires you to always have the phone charged and have internet connection. A few days into our stay, the key stopped working, and we got locked out. The person at the emergency phone number couldn't help us. So we had to send a message to the host and wait for him to solve the problem.
2) The apartment wasn't clean when we arrived. There were bread crumbs in a drawer in the bedroom from the previous guests. The floor was dirty. Lots of dust on the floor and especially under the beds. The rug was filthy. We complained to the host about this, and he didn't take care of it.
3) The bathroom sink was clogged, the water wouldn't drain properly and filth from the tube was coming up to the sink. Disgusting stuff. We complained to the host, and he didn't do anything for days until I went ahead and complained to AirBnB. That called his attention and finally, 5 days into our stay, he sent a maintenance to fix it.
4) The TV didn't have a remote control. We couldn't use the TV for days, as we complained to the host and didn't do anything about it until I complained to Airbnb. On our 5th day, the maintenance guy brought a remote control.
5) The internet was weak. You can't do video calls, the image breaks up. Host didn't offer any solutions. If you need to work remotely or communicate with your family while you are in this apartment, forget about it.
6) The apartment was cold. The bed covers were very thin, and we were cold at night. We asked the host if there were extra blankets that we could use, and he said he never provides his apartments with extra blankets. Since we don't travel with blankets, we had to use towels and jackets to cover the bed.
7) While the host always responded very fast, his responses were polite empty promises, but he didn't do anything to fix the issues. It's when I contacted Airbnb that he fixed 2 of the issues (not all of them).
