A person wandering in a strange city, where can I wash and sleep?

If it is only an expedient measure, you can choose places that are open 24 hours a day, such as McDonald's and KFC, Internet cafes, bus stations, railway stations and airports. Except Internet cafes, all these places can have a free night's rest. At the same time, they all have indoor places and toilets to keep out the cold. If you really need a bed, spend money. There are cheap youth hostels, and several strangers live in one room. It is more expensive to stay in a hotel.
