I'm going into my third year of IP in September and I would say it really depends on what your interest is and whether you want to do IP as a career choice or just as a gateway degree to any career field. As melboudi says, it's not too demanding in terms of actual hours but you do get a lot of readings and such every week. The first year isn't so fun in terms of electives (you have to take really general ones plus two rather standard core modules) and the second year gets better in term of IP-related electives; however, both years are quite random in terms of what your experience will be like specifically (eg. your tutorial could end up having 2 out of 15 people attending the whole term, or your tutor could be really inaccessible and detached when you want support). Overall, I can't really complain about the teaching staff but I do wish the assessment were not entirely subjective (which it appears to be, leaving your mark to pretty much lottery-like odds) and I certainly wish the admin side were better. It's July and we still have no information on 3rd year module choice, disso requirements and deadlines, or anything else!
On the whole, if you're into IP as a field, I think the City course will give you a good overview and prepare you for further study if that's your aspiration. However, if you're just considering IP as a gateway course to get the transferrable skills everyone seems to need these days, I'd suggest you choose a more respectable university, as ultimately that'll probably have more effect on your chances than the particular course you did.
If you have any particular questions, drop me a message and I'll be happy to tell you more if you want!
*ETA: If you're doing just IP without Soc, then there are in fact three core modules in year 1 and one elective (or two electives if you do a language). The core module I forgot to count is actually the really interesting one! Sorry about that.
