Katrina and her family made our stay very easy and pleasant. They have a wonderful house and the room we stayed in was perfect for us. You can reach the main sights in London easily via bus or metro - both are 5 (bus) to max. 20 min. (metro) walk from the house. Katrina and her family are all welcoming, very nice to talk to and also helpfull regarding tips for your stay in London. I can highly recommend it!
