If you're looking for a sweet place right in Hackney Central, look no further. Juliette is very kind and attentive to her guests; communication was quick and easygoing. There are several rooms in her house available and I stayed in two, both of which were good (even the "small" one was reasonably spacious). Kitchen is well supplied. Bright living room for reading / casual work.
The famous Ridley Road Market in Dalston is about a 25 min walk, highly recommended (e.g. 1 pound for 4 large avocados!). Broadway Sunday market is also nearby. Otherwise there's shops literally a minute away.
