This place is great!
First, it is wonderfully decorated. It makes you feel like you're staying in an ultra-hip but comfortable space.
Second, the location is very convenient. You're 2 seconds away from Bethnal Green tube station which is on the Central line which runs all night on Fridays and Saturdays. Also, within 5 minutes walking distance or less are a number of great bars, cafes, and restaurants. One minute away is the super hip street Paradise Row with a number of new restaurants and bars. The area is safe.
Third, the place is super clean. Huw maintains the place very well. You'll have all the things you need to make your stay comfortable - plates, cutlery, etc.
Fourth, Huw himself is great. He was very communicative and offered lots of recommendations on places to see and things to do.
Cons: The noise from the street can get a bit loud at times at night so if you're a very light sleeper I'd recommend some ear plugs. The beds also are just spring mattresses so they're soft. If you're looking for something really firm and need your memory foam, this won't be your best bet.
Overall, such a great place. Grab it if you can! We'd definitely stay here again if we come back to London.
