Gilly is extremely friendly and helpful. Her place is exactly as advertised! It is cute and clean and a great alternative to a hotel. She was right beside the bus stop which was amazingly convenient (especially when we really got the hang of all the transportation options London has to offer). Would definitely stay there again!
If you're travelling with someone who is a bit older and has difficulty lifting their bags up flights of stairs, my only suggestion is that you take Piccadilly to Hyde Park Station and then take the 137 South to Battersea Park. The bus ride is a bit longer but you won't have to lift any bags!
