We had a great time in London and it was centered around Lisa's flat. In the end, that's what it's all about. There is so much to do all around London, so what location you are staying in doesn't really matter as long as it is a safe neighborhood and is nearby a tube/train station. If you're mapping this place, we used the Haggerston Overground station for all our trips. It's about a 5 min easy walk from Lisa's.
The flat itself was perfect for our family of four which included us two parents and our two adult (20's) kids. We ate breakfast every day there and made a couple of dinners in the well appointed kitchen. Wash machine worked great for the one mid-vacation use we needed and the clothes dried easily outside in the private backyard on the line.
Yes, we survived London's hottest day ever recorded. Yes, it was warm in the house as there is no AC, but that's typical for London. Our hot weather is not the norm (we'll, hopefully it won't be). But, with the windows open, fan running in the bedroom it cooled down and we slept well.
Communication with Lisa was excellent. This was our first use as Airbnb renters and Lisa helped us through it all, including when we were still figuring out between her property and others. Directions to her place from the train station were accurate and easy, even with carrying roller suit cases.
All in all, this place was great for what we needed. If you are there on a Saturday morning, don't miss the nearby Hackney Broadway farmers' market. We were lucky enough to be there on two Saturday's, where we stocked up on fresh veggies, eggs, jam and cheese. Great prepared foods there, too. Other convenient stores nearby for everything else you need.
