I've seen plenty of rooms on spareroom.co.uk advertising rooms with that price. They don't look great, and some don't even have desks. Has anyone rented a room with that price before? By Central London I am refering to zones 1-3.
That's a REALLY good price for London.
From stuff I've seen online, £400 a month in central London will barely get you more than a cupboard, lol.
There are areas in Zone 6 and higher that are reasonably commutable if you're close to a fast train route and can afford the travel card.
