The flat is located in the basement, there are 2 small windows that lead to the street so you can literally see people's feet as they walk by.
It's also very noisy, especially at night, you would wake up every time a car passes by.
The flat itself is old and the furniture is old. There is no washing machine.
To take shower, you have to turn on the heater and wait for 30 min. The hot water is enough for 4 min shower. The second person has to wait another 30 min.
There is only one small electrical heater, so it was pretty cold, especially at night.
But our biggest problem was bed bugs. I had awful bites all over my hands, legs and face. We had to move out 2.5 weeks early. I have a medical certificate confirming that this was bedbugs (not mosquitoes or any other kind of rush). The host didn't try to help or find a solution. He said there were no bugs in the flat when he checked, but surprisingly, the bites stopped when we moved to another property (with the help of Airbnb support).
