Hi I'm at wimbledon not chelsea tho had some friends there.
Stuff to know for travel, buses are a ten min walk from the accom, not big but adds time to comute, tube is 30 min walk! and overground is as well. it makes comuting to pretty much any uni and esspecially central london 1 hour to 1 hour and a half!
so be ready for this, as for the place itself rooms are honestly really nice loads of storage and colourful (lime green or orange) ive seen a lot worse from london uni accoms. id say thats the only thing in its favour tho as the common areas are barely used and is basically a glorified entrance way (theres a gym but i dont work out so wasnt useful to me) theres a smoking shed outside where a lot of socialisation happened so if thats your style but I dont smoke so cant say if it was any better of a social scene. also theres only one vaccum for the entire biulding so do bring one, the kitchens have no windows or seating and are very stuffy in the main biulding floors C and D so be ready for that if your in that block
the biggest problem was probably the loacation, the noise of the school it overlooks (only a problem on lower floors) and the lack of a social scene which is to do with the location and lack of social areas (seriously no seating in most kitchens they are galley style so basically a corridor you can barely move in) if you socailise a lot at your uni and you can deal with commute its a fine accom, not for the price but thats just london!
The rooms are seriously really nice tho loads of storage, a mini fridge in your room! and ensuit bathrooms, I've got a much worse room in my flat this year!
