We loved our stay 'The Studio'. Stefan is very amiable and nice to deal with; and the studio itself has been designed with style and good taste. There is a remarkable amount of just-right useful stuff which all has it's place in a very organized manner. The bed is extremely comfortable and the duvet had a lovely, quality feel - not like the cheap ones so many hosts throw in their rentals. Plus the all-important wifi is strong and the shower is quite possibly the nicest shower I've come across ever (I really didn't want to get out!)
I know London pretty well but St. Margarets was new to me and a very pleasant surprise. There's good service through Richmond to Waterloo on the train and the Fulwell night bus comes quite close (handy after a rather late night out in soho!)
We had a fabulous stay and I would definitely return.
