Expect great service from Sam, responsive and friendly.
We were 2 couples that stayed for two nights and it was a fun and relaxing experience though some may not be used to the bargelife bathroom. The beds are super comfy and the barge itself was clean and well maintained. Location may vary but we stayed a short walk from the tube stop. It was in quiet area that suited us fine as we cooked and ate on the barge(though there are some restaurants close by).
