1 room single room

Hello,
I am currently living in a shared apartment with two other people and I intend to move out ideally as of 1 September (or at the latest 1 October).
Being the person on the lease, I am looking for someone who would be ready to take it over while keeping the two people already present in the shared apartment.
The total rent is 2495 CHF (charges included) and having a much larger room with a private bathroom and bathtub, the share of the rent to be taken over is higher than the other two (1015 CHF / month).
