Samantha’s place was great for my stay in London. The bed was comfortable, the room was big enough for my things and the bathroom was nice.
I will say it is under a flight path so might recommend some earplugs if you’re a light sleeper. I didn’t personally have issues but could be an issue for some.
The bus is very easy to catch from the top of the street into central london - the tube is a little further but still walkable for me.
