I stayed 4 nights with a friend of mine and it's been the best place I've been so far in London. It's a little bit "out" for the turistic standards but with a 20 minutes trip by train you can reach Charing Cross or London Bridge. Matthew is been so kind and helpful, giving us tips for places to go shopping or where to eat. He sent me every information I needed to get there and provided us with everything we needed (You saved my life! I forgot to bring my hairdryer from home! :D ). The beds were confortable and the rooms clean and neat.
Highly recommended!
