The host was awful: rude and unprofessional.
I live in Airbnb 300 days straight (you can check my profile) and that was the worst host so far.
he never tried to help us with our issues and only blamed us that we're not using the apartment correctly.
the main two issues:
1. the heater tank was broken. It gave hot water only for 3:30 minutes
2. the electricity system was broken as well. you cannot cook anything and have AC turned on at the same time. so, basically, you should only use a single electricity device at the same time, not more. so you cannot have a shower when the stove is enabled, or you cannot turn on another AC in another room. The host said it's not a problem, just wait with the shower
