I live just outside Brighton and work there, just a short trip over the south downs in every morning. Our office is on the border between the city centre and kemp town so ideal. Not sure I can help that much really but here's the good and bad as I see it:-
Good:-
I've been to quite a few places in the UK and from my point of view there's no place like Brighton. It's very open minded, people are very tolerant and you get a diverse collection of people here. It's brilliant in the summer with so much going on. Brighton Festival lasts all of May each year and there is loads to do, especially for families. It's in a really good position, if you're like us and just outside you get the best of both world's, you can be in London within an hour on the train and you can be in Brighton within about 15 minutes on a good run (avoid the A23 like the plague in the summer, it just becomes a car park).
The cafe / bar scene in Brighton is fantastic and there's loads of organic and alternative food stores and places to eat. A night out in Brighton is just brilliant in the summer, mooching around the bars etc.
There's some great places to take kids as well, Hove Park, Cycling along the sea front from the Marina to Hove, Queens Park are all good. Weather is pretty good as well and then there's obviously the beach (shame it's not sand but there you go

) Plus every now and then you get a FatBoy Slim concert

Surrounding area you have the South Downs, loads of golf courses and the countryside.
Now for the not so good:-
As with any city some of the areas leave a lot to be desired and Brighton has its share. Travelling in the city by public transport is relatively cheap but taking your own car is a nightmare, especially in the summer. Brighton council seems determined to dig up the sea front road every year as soon as the first tourist arrives, even if there appears no need. Parking is hideously expensive and getting across town when it's busy has taken me up to 40 minutes before (about 5 miles). Living in the centre of Brighton is quite expensive as well although prices have fallen back quite a bit lately.
As much as I love Brighton, I personally couldn't live in the city itself, just outside is perfect for us. Let us know if you have any specific queries, don't know if the above will help much really, hope it does though
