I really enjoyed staying with Gerry. I had everything I needed and you can tell he works really hard to keep everything spotless, tidy, and in working order. He offers a lot of books and information about things to do in the area, and I had a couple of very nice chats with him. I can't recommend his hospitality enough!
One note to the location - it is an extremely convenient to get to Liverpool Street Station from Gerry's place and there are people all around. Just one block away are some very nice pubs and restaurants. However, you may run into some addicts and some people down on their luck - just be aware and keep your eyes open!
