23 year old guy looking for accommodation in Venice from September

Hello! My name is Maroš, I am from Slovakia and I will be coming to Venice for Erasmus+ Programme. I am searching for a place to live for five to six months. I am searching for a peaceful place to live but I am open minded and right now I would accept any type of accommodation. I am quiet and studious but very flexible as I can get along with anybody, my field of study is computer science which I study in Brno at Masaryk University. I can pay rent through Erasmus scholarship and I also have a part time job with an IT company situated in Brno. I will be staying in Venice for five to six months starting in September and ending in January/February. So, I would like to rent the room from September till the end of January or February. If it will not be possible like this, I
would be open to making to contract for longer and if I leave sooner I will
take responsibility and find some replacement for myself. 

p.s.
I don’t smoke, don't have any pets and I am tidy person. I would like to spend most of my time getting to know Italy, Venice and the culture here.
