Can't recommend this place enough. It's a v pleasant, cosy flat, with a stunning attention to detail - from the tiling in the bathroom and kitchen to the small outdoor suntrap to the individual shelving units. The kitchen is excellently equipped, the TV is vast, and the bed is probably the most comfortable I've encountered in an Airbnb. It's part of a block of flats, but was extremely quiet day and night.
Nick was v helpful and always responded quickly to queries. And when I had to attend to an ill-timed emergency on the last day of my stay he was incredibly understanding about the checkout procedure.
Newington Green is a lovely spot, as anyone who has visited will know. Great pubs, restaurants and cafes on your doorstep, easy access to Stoke Newington, Dalston and Islington, and good bus links to much of the rest of London.
Highly, highly recommended.
