I used Ashkin's flat for accessing the Olympic stadium, and it was perfect for the purpose, particularly as there are hire cycles right outside the flat, which meant the journey could be completed in under ten minutes.
The flat itself provides a comfortable home away from home experience, for your time in London.
The person less check-in is very straightforward and makes arriving and leaving simple.
Communication with Ashkin was excellent, and I would be happy to recommend the flat to anyone.
