Would definitely recommend Will's place to anyone looking for a place in London. Though I didn't get to meet Will and only briefly met Tony, the two were very easy to contact and were very helpful whenever I needed anything.
The flat couldn't be any nearer to West Ham tube station, it's really accessible and easy to get to. The room is nice, spacious, and clean, and the communal areas are good too. The only possible downside is the flat not being in the centre of London (although the location itself was fine) so it might not be ideal if you're wanting a central location but it's so easy to get from West Ham to the centre anyway that I wouldn't consider it a problem and I think the money you save from not staying in the centre easily outweighs the money you spend on the tube.
Overall I would definitely recommend it here, if you don't mind having to get the tube into the centre then this is a really nice room run by really helpful fellas!
