It is relatively easy to get to Richard's place. Just get out from the Upton Park Station and walk for around 15 minutes (with luggage) and you will get there. I have stayed at this place for 2 nights. The room is really tidy and warm. Even though it is not allowed to use the kitchen, you can have dinner nearby. There are many restaurants and supermarkets near the station. It is no way for you to being hungry at night. Also, Richard and Oakki are so nice that they treated me snacks and a bottle of water :)
