Firstly, Rosalyn was a fabulous host - great communication, helpful little things like a spare set of keys, offer of an Oyster card, a bowl of tangerines and delicious apple juice. The flat is really characterful, an amazingly well-thought out little space with a sunny private courtyard. the flat is on a really beautiful London square, including a gorgeous central garden (accessible with Rosalyn's key) - of course, this was all made completely wonderful with a weekend of brilliant sunshine!
