Great stay. Mun is so nice, helpful and responds really quick to questions. She will personally check you in and show you around.
The house is very clean, Mun comes in everyday to check and clean. The flat has everything you need, both in your room and the kitchen and bathroom. The room (1 person) is really big as well.
The location is really nice and convenient for central London. Do check out the various historical docks and walk the Thames path, it isn't far from Towers Bridge at all and makes for beautiful sunsets. Public transport is nearby and takes you to central London in about half an hour. Shops and supermarkets in walking distance.
So go and stay of you're looking for a quiet, clean, stress free stay. Basically the only problem is, it is usually booked ;)
