I have an idea how to compete with AirBNB
Hear me out…
We buy a large building, split it into like 400 rooms… each room has its own bathroom, maybe a fridge.
No kitchen because who cooks on vacation anyway?
Rent each room by the night. Someone comes in the morning and cleans it for you, makes the bed and it’s INCLUDED in the price
No hidden cleaning fees, booking fees, no bad ratings from mom and pop operators
We’ll call it HAAS (housing as a service)
Who’s in?
