Our entire holiday was turned into a nightmare because of this airbnb.
We arrived to discover there was no hot water or heating. The bedsheets persistently felt damp because it was so cold, we had to wrap up warm in outdoor clothes to sleep, and then we couldn't shower or wash properly either. We had a young child and it was extremely difficult to manage.
The host delayed us constantly. Promising an engineer was on their way, then telling us they've been delayed repeatedly, only for it to reach a late hour and the engineer not to turn up. The excuses changed each day, but always managed to be believable enough for us to continue to give the benefit of the doubt until it got too late in the day for us to make alternative arrangements.
After 3 days we finally had enough and although further promises were made that things would definitely be fixed ASAP, we did what we should have done on day one and moved out, though it was hard to put the stress behind us and enjoy our remaining days.
