That's a nice spacious room in Lambeth borough. The bed is comfortable and host is very nice and hospitable. There is underground in around 15 minutes walk and couple of bus stops in around 5 minutes walk. Some small cafes are around and it's easy to go of foot or commute to main London sightseeing.
Please note that Britain has it's own standard for power plugs. Iben luckily had an adapter for me :)
