We stayed here for an event at the O2 as it was the cheapest, decent option we could find. It was very conveniently located for the O2 Arena. Pub closed at 1am but was very tame even though it was Saturday night and the area generally was quiet for London, with no noise issues.
Accommodation is new and modern throughout. Room was on the small side but big enough for one night. Bed was comfortable with good bedding. Breakfast items were provided which was unexpected.
Some minor issues prevent this being a perfect stay: 1) The breakfast items include 2 orange juices, one of which was already opened and a small sip taken, so was a little concerned on hygiene. 2) Some other cleanliness issues, e.g. hairs in the bathroom drawers. 3) There was a green light which had obviously annoyed another guest, so they'd stuck an 'Oat So Simple' porridge lid over it. Initially thought I was seeing things when I saw a foil porridge lid on the ceiling!! 4) There seemed to be some sort of water drainage issue as the carpet directly outside the bathroom was constantly damp, felt like it was under the carpet. They should get this looked at before it becomes a bigger issue.
Overall, I would consider staying here again if options were limited but wouldn't seek it out specifically.
