The flat worked perfectly for my group's needs. My friends and I just wanted somewhere to use as a base that was well-connected to Central London as well as not being extortionately costly!
The apartment itself is great. The second room is a little cosy but that's to be expected in London properties. Loved the décor as well as all the supplies provided. A word of warning though that there are 61 steps (we counted!) between the building door up to the top floor apartment and no lift available - something to bear in mind.
I have lived in East London so I knew Bethnal Green to be a lively location - plenty of cool spots, from brunch places to nice pubs. It's also situated near Victoria Park which is a beautiful green space if you get the chance to explore. Bus routes and the nearby tube (Central Line) allow you to get anywhere in London with relative ease.
It's been mentioned in other reviews but the train line being so near could definitely disturb lighter sleepers or those who prefer to sleep with the window open but our group didn't have an issue with this.
Overall, would definitely recommend the property and a big thanks to the kind staff who help Kate run it!
