Since a friend of mine was having a wedding in Hiroshima, I decided to book this hotel based on price, using a welfare website that I am a member of at work.On the day of my stay, it looked like I would be arriving later than originally, so when I called the hotel and told them that I would be arriving after 9am, the person at the front desk (male) said, ``We will be arriving at the hotel after 9am.'' I was surprised and asked, ``Do I absolutely have to arrive before 9 o'clock?'', but in a rather strong tone I was told to listen to the end of the conversation. I was told, ``That's only if you pay in cash, and the front desk will be closed at 9 o'clock, so if you pay in advance, like you, please prepare your room key in a key box with a combination lock.''I was relieved, but if that was the case, there was no need for him to say that first thing to me, who had nothing to do with him. I thought so.When I checked in after 9 o'clock, the refrigerator was shared in the hallway and there was no washlet, which is a rare facility these days. I read the precautions when staying, but the next morning after 6am, I accidentally locked my key in the hallway when I tried to use the refrigerator.This was obviously my mistake, but when I went to the front desk thinking, ``Well, it's morning and people will probably be at the front desk by 7-8 o'clock,'' the front desk's notice said, is from 13:00 to 21:00, and if you lock in, you will need to pay 5,000 yen for an employee to respond.''I was a little hesitant because it was quite expensive, but at 1pm there was a chance that I wouldn't be able to make it in time for the wedding, and there was no air conditioning around the front desk, so it was quite hot at 33 degrees Celsius, and I couldn't stand it as it was. So I decided to ask for the lock to be unlocked. However, there was no phone at the front desk and my smartphone and wallet were in the room, so I went to a nearby convenience store and asked the foreigner lady working there to borrow her phone and ask her to unlock it.An employee came on a bicycle in about 10 minutes and unlocked the door. No receipt was issued.I chose this hotel because it was cheap, but due to an unexpected mistake, it ended up being expensive.If you are considering using this service, it is recommended that you pay attention to the facilities and the reception hours of the front desk.This time, it was a very memorable trip where I went through the process of losing money by buying cheap items.When the foreign lady at the convenience store went to pay her phone bill after unlocking the door, she declined. Thank you from the bottom of my heart for helping me when I was in trouble.
