I stayed at Lea's while attending a 3-week summer school. The listing was as described, if not better. The room is full of light, cozy and comfortable. The apartment is in a really well located street that is close to all of the action, but quiet at the same time.
Lea's flatmates are super nice - we went out a couple of times. They were really helpful on a number of practical issues, and so was Lea. Communication with all of them was prompt and flawless.
The neighborhood is already well known, so I guess it would match the expectations. It's very lively and full of interesting bars, restaurants and shops. I also had no problems reaching other parts of London by public transport.
All in all, I would very much recommend Lea and her place for a Shoreditch stay.
