All in all a perfect experience. Charlie made sure we felt welcome by providing a lot of information. The bedrooms faced the main road, so they're a bit noisy. This was well explained in the description and nothing a good pair of noise canceling headphone remedied.
The cleaning lady welcomed us and gave us a practical introduction. As an added bonus we got to spend an evening with Charlie and his lovely mother in company with Monty Python at the O2.
As a tourist wanting to see many different parts of London I would personally wish there was a tube station a bit closer, but this is also something we knew in advance and you really can't expect Charlie to reroute the Victoria line now can you? ;-) Bus stops are very close though.
5 out of 5!!!
