Zimmer in Wohngemeinschaft zu vermieten / Room in shared flat for rent

Currently, 2 people are moving out from the apartment, me and one roommate. And the 3rd flatmate, Nico, is staying until July, so soon it will be brand new people in the WG.
Nico is a worker and he travels a lot. He is a very nice, chill and interesting person. He really values cleanliness, so everyone can live respectfully in the flat. So that would be an imortant point for a tenant.
The rent is 810 per month. And usually every June it increases 3-5% (so +20 euros on average)
The deposit is one month’s rent, so 810 euros.
And I would like to give my furniture that I can’t unfortunately move with me, so it should be handed over. So for the furniture it would be 390 euros.
The start of rent would be from 1st of April.
Please note, that you would need to provide a proof of income, Schufa (jetzt beantragen) certificate and optionally (that would be a huge plus) liabilty insurance. As well as passport and self disclosure form. All of this can be shared after the viewing.
Please if you have any additional questions let me know, we can organise the viewing so you can see the apartment and meet Nico.
