I lived in Crewe flats, although this was two years ago so stuff will have changed. I don't know anything like how far it is from the Edge buildings or anything, as they didnt exist when I lived there! However will spill what I do know...
Its a converted mansion so pretty and old on the outside, but was refurbished inside 3 years ago (just before I moved in) so is modern inside. Its got nice grounds and its own tennis courts, and a small police station at the bottom of the drive for some reason...
The flats are of varying sizes, there were 6 in my flat which was about average, there was a bathroom with shower, loo and sink and also a separate toilet and sink between 6 of us. There was a big kitchen with ample cupboard space and a big kitchen table. As its converted, the rooms are of quite varying sizes, so you could be unlucky and get a smallish room (still ok though) or be lucky and get one which could fit a couple of double beds in and still leave space! Oh theres a sink in each room too so dont need to wait for the bathroom to brush your teeth (not that I ever had to wait anyway, I think I had to wait a few minutes for a free bathroom about twice in a whole year).
Its a quieter accommodation as its fairly small, you get a fair few 'semester abroad' students staying there, there were always a few Americans and Australians around. Theres a common room with pool table and table football as well.
oh and theres a photo of my room at crewe and our kitchen on the second page of this old thread if you're interested:
