Flexible Contract Room, Quite and with 24h heating

Hello my name is Marianna. I am originally from Greece but have lived in London for 13 years, I am also PhD educated. I am looking for a big double room for single occupancy in a quite and clean house. I am working/ studying from home and I am very easily destructed with noise, so it is very important for me to be in a quiet house it is also very important that the room has all day heating at 25 degrees, as I suffer from theroid so I feel easily cold. I am looking for a room with a desk and internet
I am looking to share with no more than 2 other people. I am interested in a flexible contract that ideally be able to leave with 2-4 weeks notice. I am looking to move in the room asap. If you have something available I am happy to hear from you.
