I booked mine on Meituan (MT), and it's my favorite guesthouse so far! It has a projector, an iron, and even some workout gear. The only catch is they charge for disposable bath towels, but that's not a dealbreaker.
A 'VIP spot for the flag-raising ceremony'? If you see that advertised, just run. Even the most important person in the world would have to queue and fight for a spot like everyone else.
