Go to your boyfriend and book your own hotel.

He booked a bad hotel, so he may have limited financial conditions. Now there are many group buying networks, which are cheap and the conditions are not so bad.

The next time he says he wants to open a room, you say, "Let's find a hotel with a better reputation." You can tell him that if the sanitary conditions of the hotel are not good, it will be bad for your health and even get sick. This is not to scare you. It's not just a matter of interest.
