Is This Code For Japanese Love Hotel Rooms For People Not Totally Into It?

On my upcoming trip to Japan, I am staying an extra day in Niigata as the hotel in Tokyo originally said they have no rooms available on one day.

Then, just a short while ago, I received an email from them which said in part:

About 10th of December We still have a room avalable at New Building semi Dabble room.
but the price is 8500yen. Please book it if you like it.

Thank you very much and we are looking forward to seeing you soon.
