It kinda depends on your course. Some facilities are better than others and that greatly affects how you feel about the univeristy.
I do engineering and I am in the brand new building. The building, despite having a few cheap-spots, is generally really good and it makes it a pleasure to go there each day to work. The other engineering buildings aren't so nice and they're quite old. Similarly, most of the other facilities are quite dated and so it might not be the best atmosphere. It is really up to you to go along and see it for yourself.
In terms of accommodation, there is an okay selection. There are some shabby ones, but they're starting to modernise this area too. Victoria Halls are about the same cost as Singer and quite a lot nicer. Obviously if you're the first to live there then it will be superb. Unfortunately there are some buildings which are really dated and ugly (such as Priory) and most people hate living there. It depends if you get lucky.
Overall, I have enjoyed my experience so far. I am looking forward to moving into my own house next year with friends. Most people on my course have enjoyed it too.
The only way to really know is to just come along and check it out for yourself. It's about what you're willing to live with.
