We had three great days in London and this place was perfect for us. Jamie is a very nice host, very helpful and communicative. The apartment is about 15 minutes way from central London, not too fat and not too close. Great breakfast restaurants nearby.
Yes, our bed was a bit hard but for us that was perfect - slept like a baby :)
I would definitely recommend James and his apartment if you want to explore London and want to rent a place where you avoid any problems. We especially want to thank Jamie for meeting out somewhat akward checkin and check out times :)
(Oh - and do get tickets to the ABBA Voyage concert. It was spectacular!!! 6 stars out of 5. :) )
