Great location, right across a train station with good links to Central London and bus services to North Greenwich. The room is spacious and clean, comfortable bed, secure access. I didn't use the kitchen but it seemed stocked with lots of things.
The bathroom is by the entrance, private but very small and not really well-looked after (it was very clean, but there were maintenance issues). In any case that wasn't a major issue for my stay and overall I'd say it was a great experience.
