Hotel Hot spring Shime

This place is close to the domestic airport but far from the international airport. it's inconvenient if you have heavy luggage. in the surrounding area there are some restaurants. The room is quite comfortable but it is cramped to open a large luggage. they provide free toiletries and there is all-you-can-drink. But There are 2 things that disappointed me 1. I made a mistake and made a room reservation for 1 person and made a telephone call if it could be change for 2 people. The male staff on the phone offered an upgrade and I had to pay 4600 yen. I agreed and said I would arrive at the hotel within 2 hours. But when we arrived at the hotel. At front desk there were 2 female staff who didn't know at all about the reservation I made and the changes. The female staff recalculated and I had to pay 4800 yen. Their additional fee is 4400yen + 400yen (accommodation tax for 2 people). Which is different from the phone. When i ask why the additional fee different from the one called? the female staff said it was because there were two of us. But I already paid in full for 1 person and I should have paid as said on the phone. Since I'm too tired from the trip to the hotel and had early morning flight. I just let it be. 2. While resting, I heard a noise and it turned out the sound came from the AC in the room. Even though we didn't use it, the AC made noise all night. I was quite disturbed and lack of sleep for front office staff: it is better to speak slowly but clearly than fast but hard to understand.
