I've got 3 properties rented to students (in New Zealand) and love it (2 x 4 bed, 1 x 5 bed).
Yes, they are messy. Yes, they do not look after the house in the same way that you or I would. Yes, there is usually minor damage to be repaired like cracked windows, holes in walls, etc. though the bond should cover this.
On the plus side the rent is generally paid on time and is higher than a rental to non-students, students are easy and fun to deal with, vacancy is 0 days if you plan the advertising sufficiently in advance, the property does not have to be entirely salubrious and can have worse parking/access than properties rented to non-students without impacting the rental income.
