We are on holiday over Christmas/ New Year. We arrived in our air bnb and I went and got the shopping and then came back and tried to light the gas oven. Host had gone off to a work emergency so not been able to meet us so left the flat unlocked and sent me the building code. I messaged to discover how to work said oven and she replied saying use a lighter near the gas pipe and near the hob, absolutely fine. No lighter to be seen so we have a look in drawers and cupboards to try and find one. All in open spaces. We find a gun in the bottom drawer of a unit next to the front door and a razor sharp small knife in the room my daughter is sleeping in. (As well as what i would consider to be drugs paraphernalia. Baggies rolled up tin foil etc) we are quite alarmed by this and admittedly have no knowledge of guns or knives. Gun clearly states not a toy and doesn't feel light weight or flimsy and that it can cause serious injury or death. As we haven't met the host or had a similar situation before so are unsure of the language barrier etc we choose to contact air bnb as oppose to host for advice. They refund us and put us in touch with their security team. We leave the air bnb as the local rebooker promised by air bnb isn't forthcoming and we receive an email to say they have updated the host. Not wanting an interaction with a stranger who is now annoyed and with a freaked out 12 year old and wired two year old we head to a nearby(ish) hotel. Host has since messaged saying it is a toy gun that shoots rubber bullets and we have caused her financial hardahip so my AIBU is did we over react and should we be reimbursed for the accommodation this evening in the hotel? (Air BnB gave us a refund (via email) and we have rebooked from tomorrow but it was after 21:00 local time and nothing available on air bnb that was suitable until tomorrow) We are also absorbing the cost of the more expensive air bnb and the loss of food which may perish that i brought at the supermarket. Interested to hear others opinions. Generally quite a laid back family who have used air bnbs all over Europe but never experienced anything like this.
