I chose this place primarily because it is very reasonably priced and the location is good: it was very easy to get to the subway station and to other places in London. Having a bathroom was a huge bonus (and it has a great tub!). My only surprise was that I found the traffic noise to be quite loud, but that may be because I'm fairly noise-sensitive. If you're the same way, I would recommend bringing earplugs.
There are also shops and good places to eat nearby, so lots of conveniences.
