I stayed during New Year's and the first two weeks of January at this wonderful room. It was large, bright, clean and warm. Bathroom and kitchen was a flight of stairs below, equally clean and functional.
As a deep sleeper, I didn't have any issues with the noise from the street.
The area is fantastic with plenty of little restaurants, cafés, barbers, grocers, a large Wsitrose nearby and off course the tube station.
For me being close to Highbury Fields was important since it was perfect for my jogging routine.
Would come back!
