Below issues happened during the period we stay in this listing:
1) There were water dropping from the second floor to the first floor and water leaking from the fridge at the first floor for a several nights during our one-month stay in the listing. We found the floor outside our room was all wet and even flooding into our room when we woke up in the morning. It is would be very slippery and would be very dangerous for us if we were not aware the wet floor when we just woke up and walked outside our room.
Such water problems repeatedly happened throughout the whole month we stayed in the listing. The host was even not in London when the problems happened and he was not able to fix the problems when we finished our one month stay in this listing.
2) The host did not have any arrangement on trash disposal and just left the trash accumulated in the trash bin in the kitchen shared among the host himself, us and another guest in the listing. We helped to pack the trash in plastic bags (which half of the trash in the trash bin was accumulated BEFORE we moved into the listing).
The host wrote in his message to me through Airbnb platform that there is no cleaning services in this listing and he said he cleared the trash bin for us as courtesy. He said "it is not mentioned anywhere in the listing, cleaning will be part of the fee". However, I found I was charged "cleaning fee" as shown in the Airbnb receipt!
Further, the host wrote to me "everyone should be responsible for their waste". But the host never willing to tell us where and how to dispose trash according to the local laws and regulations (as far as we understand, there should be designated trash bin for each household in London to dispose their trash).
3) One morning when we woke up and walked out from our room, we found there were chicken bones, chicken skin, shoes, socks all lay on the floor of the shared kitchen. It was very oily, slippery and dangerous for us if we were not aware and just walked into the kitchen when we just woke up in the morning.
All these above issues were officially reported to Airbnb.
