Before I ruin my precious night's sleep, I am writing this review in hopes that it will catch the attention of those who are considering staying at this inn.I made a reservation for a whole house on a certain reservation site in July.In conclusion, I did not stay overnight. Actually, it wasn't in a condition where I could stay overnight.I didn't receive any information about how to check in, so I called them on the day of the check-in, but at that point it seemed pretty suspicious, and I should have noticed earlier because there were a lot of bad reviews.On the phone, I was told that the cleaning part was not available today, so the owner was told that the cleaning was scheduled to be done or that it wasn't finished yet. At this point it was already past 3pm.I was talking to a friend about why the cleaning hadn't finished even though I knew I had a reservation, but as I was told, I decided to go elsewhere to eat or shop until the cleaning was finished. When I went to look at the room after 7pm, I found a messy bed and trash left behind by the previous guest, as shown in the attached photo. A used cup left in the sink. No matter how you look at it, it wasn't even cleaned.I tried to ask what was going on, but I couldn't find the owner, and when I called, he wouldn't answer. I called the reservation site to check, but the owner came out from the hotel we shared downstairs.I couldn't get through to the phone, and when I asked what was going on, the cleaning wasn't finished, but my phone had recently been stolen, so I couldn't access the reservation site and couldn't answer the phone. My part-time worker isn't home today, so I'm cleaning. I ended up making excuses.It is a mystery why they are accepting reservations even though they cannot even check the reservation status.No matter how I looked at it, I didn't think any cleaning had been done, so I went to see the site with the person in question, and he said, ``Oh, they hadn't done that.''There was no apology, and in the end, even the guests, including myself, were asked to help with the cleaning.The conversations don't fit together and are all incoherent. I don't know the number of people who had made a reservation or their names, and the owner is elderly, so I guess...I couldn't even relax if I was waiting for cleaning after 7pm, so I canceled Poseidon and moved to another hotel in a hurry.For the group of young men staying at the shared hotel earlier, please be careful as the owner is dangerous. He was eating our food without permission. I received this advice, so I think it's fair.I can't help but wonder why such an inn is still available for reservation.I think you should resign if your business is in questionable condition.
