Executive summary - Avi's place is a gem.
The bedroom is well lit and curtains keep it dark if you like sleeping in pitch dark. The living room is spacious with a massive led TV and a fully equipped kitchen. The highlight of the flat, with no doubt is the shower, must be one of the best showers in London!
The location is perfect - 2 mins walk from an overground station, 4 mins walk from a tube station. The neighbourhood felt safe at any time of the day. There are Tesco, Saibnsubry's, a few cafes and at least 2 decent bars within 3 mins walk.
The only possible challenge that I can think of is getting heavy suitcase up the stairs as its steep and narrow. Other than that, I wholeheartedly recommend this flat!
