Hey second year here and you should definitely consider private halls. Been living at Goldsmith Court for two years now and have rebooked for my third. Viccy is nice but I reckon you get more value for your money at Goldsmith for only a bit more. A lot closer to City campus (literally across the road from Newton), bigger rooms than Viccy, nicer kitchens and TVs, etc.
There really isn't that much difference between Goldsmith and uni halls. The majority here are freshers (with it being seconds away from uni), we get fresher reps and a halls committee like the uni halls too. Really good value for money when you take everything into account (Gill Street's rate is crazy, especially since the rooms and kitchens are bigger at Goldsmith).
Honestly don't waste your money. If you want to spend more go for Gill Street South or Byron, seeing as they're brand new. Gill Street's popularity is based on its reputation as being the closest uni halls to City campus and being the most expensive. That won't last now though due to the two new halls.
Hope that helped.
Had/have mates living at Viccy and haven't heard one complaint about lack of freshers.
Also at Goldsmith the majority of people are freshers since we're so close to the uni.
A lot of people seem to get scared there won't be many freshers at places like Viccy or Goldsmith but that simply isn't the case.
Goldsmith's across the road from the uni, Viccy is about a 15 min walk. Surprised by the lack of mention for Goldsmith actually haha.
