The apartment was in a very bad condition when I moved in:
1. There were over a hundred flies all over the apartment. They flew in through the open windows but the owner did not clean it up.
2. The boiler was running from 30 minutes to 6 hours. Constantly had to go out on the balcony to turn on the hot water and heating. The owner didn't fix the boiler until day 9
3. The bed frame is broken. The mattress moved out on the floor twice.
4. The water switch in the shower does not work. Had to use the opener to turn on the shower.
5. On day 13, the pipes clogged and shit from the toilet came out through the hole in the shower. The owner said this had happened twice and the tenants were to blame, hinting that I would have to pay. But I used the toilet properly. The water barely passed from the beginning.
I moved out on day 16. Airbnb gave me a refund for the remaining days. The owner tried to charge me for the repairs, but Airbnb sided with me and denied.
Horrible apartment! Avoid it!
