First of all Brendan is an incredible host who answers very quick and kindly. His house is in a very peaceful neighbourhood and next to everything: supermarket and shops, overground station, bus stop, gas station...
If you're getting there by car you will find park spot without a problem. And if you're travelling by public transportation the overground will get you to Edmonton Green from Liverpool Street Station in 30min.
The house is impeccably clean, beautiful and modern. Very comfortable place to be when in London, so don't doubt and rent Brendan & Sharon's place!
