The Accommodation Office runs an online data base of student accommodation in the private sector which we would encourage you to look at.
The data base is called "Cornwall Student Pad". The 2018 listings will go live on 9th January 2018
We also run a Facebook group to help Falmouth University and University of Exeter students get in touch with one another who are looking for private rented accommodation. This might be to hook up with other students to form a group, where an existing group may need another fill up a house or who have a "spare room" in house they are moving into. Please feel free to check out the messages, post one yourself or even start a discussion.
