After five years with AirBnB on four continents it was the first really negative experience, mainly the high noise levels and the host's reaction to it.
The provided earplugs and the "white noiwse machine" we were introduced to upon checkin should have made us realise immediately:
This was going to be a very noisy place!
The walls are super thin and we could hear all the activity around us. The host family with the two small kids living, screaming and playing right above the room was the first issue we encountered. Additionally, the very loud heating system started working in the room next to us from 4am onwards, after which it was not possible to sleep any more.
When we mentioned the heating issue to the host and asked for solutions, the host's reaction was not helpful at all ("But this is "white noise", what is your problem?", "Nobody has ever complained", "I almost cannot hear it, you are overly sensitive", "You should not use AirBnB if you cannot take this", ...). The host said she was going to change the heating setting, but the effect was not noticeable to us.
We would have checked out after the first night, but since it was easter weekend the hotels around were fully booked and we stayed three nights as planned.
Besides these issues, the place was exactly as you can see in the picture - a clean room for two people to spent some nights.
