Let me give you a brief answer.
A. In order to cope with the inspection, a disinfection room, a linen room and a washing pool must be set up. The linen room should be separated, and the space for counting dirty linen should be set aside, mainly to cope with the inspection. The real linen has gone up the stairs or other places.
Second, depending on the number of rooms, where is the duty room? If, as you said, only the second floor and the first floor are guest rooms, then the duty room is either set on the second floor or merged with the front desk check-in office, so that the duty room where the room attendant is located will be combined with the work room or the bathroom, reducing the space, freeing up more space to decorate into guest rooms and increasing hotel income;
Third, the bathroom should be based on the actual situation. If the first floor is catering, then there must be a bathroom on the first floor, and there is no need to set it on the second floor. If you live in a business hotel, you should consider the feasibility comprehensively. I can't answer all the information you gave me. In short, what is suitable is the best, don't waste it, and make a profit. If necessary, you can contact my QQ, and I can give you some information about the reclamation hotel for your reference, 28565663.
