It's fine if you just gotta sleep somewhere but it's not a pleasant stay by any means.
There is a pub next door which is a major source of noise particularly Thursday to Saturday and we struggled to sleep. The mattress was so worn out it sank nearly to the floor, the duvet had no cover and generally it wasn't clean. The 2 of us stayed and we were given one towel.
As I say, it's not great,but it does the job. Easy access to Greenwich and Canada water makes it convenient to travel to/from.
If I was in need of accommodation again,I wouldn't consider staying here.
