Finding Housemates

I will describe the room type briefly here.
Divided into first floor and second floor,
There is a bathroom, a shared kitchen, and a shared living room on the first floor. Other than that it is not rented out.

Shoes need to be changed on the second floor, there is a bathroom and 2 beds upstairs. Beds are double size. Upstairs and downstairs bathroom area is very suitable

One of the beds has already been booked by me

So the whole unit can be 2b2b, 3b2b, and 4b3b
3b2b and 4b3b because the landlord is considering buying an extra bed. If three classmates live in, you can also share two toilets. If four students live in, there will be one more toilet. Hope I explain clearly~
