Everything was perfect, we had absolutely no trouble. The personal support by Michael and his family was great as well. On a scale of 1-10 we would rate the flat 11. There is a Tube station nearby, so it is very easy to reach the city of London in a reasonable time. There is a small polish supermarket a few minutes away, which provides everything you need. We can also recommend Paul´s Plaice for Fish´n´Chips.
To put it in a nutshell, the Hanger Hideout is a great place to stay.
