If you are going to Lincoln University there are several Accomodation options, all of which, in my opinion are near enough to the University for you to walk to lectures (as long as you live within the city limits).
1. 1st year halls of residence - I stayed here in my first year, and the atmosphere is almost 'holiday villagesque' flats usually have between 6 and 8 residents and are fairly modern. All rooms have En-suite bathrooms so there is no waiting for a shower! When I was in the first year the internet was Dial-up, however I am aware that in my final year there was a huge petition for Broadband in halls, which I'm sure has been granted now. 1st year halls are literally on campus. There is CCTV in the street. There are some small parking areas, but not for regular use unless you have a permit from the Uni -i.e. if you are disabled. Ground Floor flats have disabled access.
There are some other university owned halls, however the ones on campus are by far the best.
2. Independently Owned Halls of Residence - There are several companies offering self contained flats for between 2 and 8 in the area surrounding the University. These are worth looking into in 2nd and 3rd years, and some of them have flats dedicated to 1s years. It is definately important to try to live with other 'freshers' in your first year if you can! Many of these halls have broadband included in rent and CCTV in the common parts of the buildings and outside areas.
3. Student Housing - provided by most letting agents in the city. Definately go through a letting agent as they will ensure you have a proper tenancy, and they will liaise with your landlord regarding any rent/maintenance issues for you. Also your deposit will be protected.
The most important thing when looking for university accomodation is to make sure you will be safe, and your agreement with your accomodation provider or landlord is formalised (e.g. you have a tenancy agreement). The University has approved providers, so it worth looking at those possibilities first. Also always make sure you view the property and make sure you are happy with it before making any agreements or signing any forms!
