出租车都是浮云

理论上，用Airbnb租6个月以上，还是合法的

我先呵呵一会

行业的直接政府机构的规定，没有法律约束？你的中介朋友的执照是买来的吧？

Renting out private residential properties
RENTING OUT PRIVATE RESIDENTIAL PROPERTIES
Private residential properties or the rooms within their premises should not be rented out on a short-term basis for less than six months on a daily/weekly/monthly basis.
Renting out the whole unit or individual rooms for residential purposes is only allowed for long-term stays of six months or more if these conditions are met:
no internal partitioning works that alter the layout of the property to create more rooms. Such overcrowding can pose safety concerns
in the case of master tenancies or en-bloc leasing-out, there should only be one single tenancy agreement per residential unit to cover the number of occupants for the unit. This does not apply to a single property or individual owner who rents out rooms within his unit to different tenants
each occupant should have at least 10 sqm of space. The maximum number of occupants in a residential unit is eight, no matter how big the unit is
includes the owner if he is living within the premises
does not apply if the unit is occupied by a family who is not renting out the premise in any way
