Overall, this was a really good place to stay. It was within walking distance to the ExCel Centre, the bedrooms were a good size with comfy mattresses and an easy to use shower. The living room is cosy, with a huge TV, the kitchen/diner is a great size, and there's a garden out back where you can vape.
This is under the flight paths for London City Airport, but we were aware of this and happy to stay regardless.
Be aware that the host can be slow to reply.
We had a couple of issues, but these are things that the host would be able to rectify when guests aren't present, and feedback has been given on these.
We would be more than happy to stay again, should we have another convention we plan to attend at the ExCel Centre.
