Hi,
I live in lincoln and have done for about 10 years now. It is a very student place as the uni has grown over the years. It is surrounded by nice country side and lots of history, like the castle and the cathedral. The night life is brilliant with lots of bars but not that many night clubs but the amount of bars make up for this as they stay open until early hours of the morining.
If you would prefer to hang out in more up market bars then head towards to up hill area where you will find lots of these types of bars. Lot of places to eat too so you are never short of deciding what you fancy, there is also a big odeon cinama but this does charge quite a lot of money as it is the only cinama for miles.
In all Lincoln is a really nice place to live with lots to do, it really depends on what you are looking for? If you want a real stundent life then try and live more in the center of lincoln or if you want a little bit more peace but still be involved with the shops, bars and party then look at a little outside of lincoln center. I live in this sort of area and it is only a 15 minute walk int town.
If you need to know anything else (like the best places to live in lincoln) just drop me an email and i will try and help
Thanks
