I was wondering if it's possible to find a decent studio in a safe are in central London for 900 GBP?
I know that a lot of people share accommodation, but I'm used to live by myself. And my budget don't allow a higher rent at the moment.
I wouldn't write off a house share if the location is the most important thing to you. Studios tend to be tiny (by my standards-- unlivable). If having enough space, a washer/dryer, stove and oven, etc, are also important to you, a house share would definitely help in keeping rent costs down! Have a look at
Spare Room to get an idea of what's available.
Apart from being in "Central London" -- what other things are you looking for in a place to live? Shopping? Coffee shops? Bars? Restaurants? Just a cozy home with none of this?
Rentonomy may help give you a better idea on the various areas of London, and the typical people who live there, which I find to be pretty accurate. The drop downs are useful, as you can easily compare rent and council tax versus crime, or areas best for families/shopaholics, etc.
Hope this helps
