The main issue is the air con is leaking water excessively. We had to have a bucket out and it filled up several times. The host knew it was broken before we arrived and made no effort to fix it.
The apartment is prone to power cuts. You cannot run more than 2 appliances at once. This is very frustrating.
There is no kettle and the toaster was broken. The single bedroom wardrobe is chained shut.
For me these issues are a dealbreaker and the host was not happy to hear about them from us. He communicated very rudely with us and did not accept that this was not how his apartment was advertised.
