Every 20-something I know in London are already living in "co-living spaces"...they're called rooms. Very common.
The idea of adults managing to convince themselves that living in dorms as an adult is somehow a good idea makes me laugh heartily.
One born every minute I guess....
It isn't a terrible idea if you're a 20something and have a entry level developer job in the centre of London and don't to commute want a half hour commute. I guess the hope is they'll only be there for a couple of years before they can afford their own flats.
The place is actually quite far off from the "centre" of London (20min commute to oxford circus, w/o changing), on the Bakerloo line (which is quite slow), and the rooms are quite overpriced, even by the local standards around here - they're so tiny*!
For £250pw (£1000/mo) you're much better off trying your luck on spare room :)
*notice the nice mirror in the pics. well played, must say.
I had to find somewhere new to live in London a couple of weeks ago, and considered this place. I've luckily found a nice studio apartment elsewhere, but I could see myself here. It's pretty expensive for what it is, but London generally is (very) expensive.
