You're staying in the store room in the kitchen, no?
The other rooms are pretty much decent. The Towers have much better rooms compared to the Block 1 or 2 (same with all Vista A, B, and C). Block 1, 2 has the freaking small room which the window faces the corridor which IMO is yucks.

I stayed in C tower last time, middle room. The middle room is quite big, well to be exact it's width is not exactly the largest but its length would be more than enough. The master bedroom is quite small compared to the other rooms, but it has its own bathroom. The smallest room in Tower suites is in an rough "L" configuration but it's not a problem either. Sorry that I can't give you the exact dimensions since I've never measured it anyway.

In short words, try to get Towers instead of the others. And for me I'd rather get an unfurnished house. Furnished units are usually overpriced, but then again they are usually very well maintained. Unfurnished houses tend to look like typical "hostels" but hey, we're there to study not to live like kings, right?
I didn't do Pharmacy at IMU hehe, but my housemate did MPharm. MPharm is pretty much relaxing compared to BPharm. Last time BPharm used to have classes from early morning till late afternoons with relatively no rest in between, not sure whether it's the same now or not as IMU has changed damn a lot since I left. MPharm however is quite a 'condensed' course and most of them need to learn extra stuff when they go over to Stradclythe. That's what my friend said anyway hehe, but he has graduated almost half a year ago and he's doing fine now 

Man, I still miss IMU... good old days.
