This was the single worst experience I have had at an Airbnb, and I've stayed in Airbnb all over the world. First, the unit has no heating, and it was 6-8celsius inside. It does have space heaters which took me an hour to assemble- they could keep the bedrooms warm but not possible to heat up the living room or kitchen, even with all 3 of the small units, they are too small.
Access was via an elevator code. 2nd night of the stay the power went out and we had no access to the apartment. Waited in the lobby for 2 hours while a locksmith broke in. Got in at 1am to find that the diesel generator keeping the building's lights on was directly below the unit. This made it too noisy to sleep and filled the place with diesel fumes. Next morning, still no power, and no ETA on power being restored, unable to sleep there. We gave up and got a hotel. I asked for a partial refund, for the nights we were unable to stay, but host refused.
