Jane's place is just steps off the bus line and extremely convenient! There are several beautiful parks in easy walking distance. Jane can also give great tips on sightseeing am can tell a lot of history of London if you are interested.
The sofa bed was surprisingly comfortable. If you are a light sleeper, you may have trouble with the trains being so close by so bring earplugs. It wasn't a problem for me though.
I'll definitely be booking with Jane the next time I'm in London!
