We stayed at Graeme's for 2 nights and had a great time! Graeme was very nice, his flat was clean and tidy. The bed was very comfortable and we benefited a lot from the collection of bus, tube and city maps in the basket on the bed table!
It's also just a 20 minute walk to the house of parliament and tube/ bus stations are a 5 minute walk away, just as the next tesco supermarket. All in all a central and comfortable place to stay in London. I would definitely stay there again, thanks Graeme :)!
