David is a good host, no problems with moving in/out. We didn't chat with him a lot - he's been busy studying on the weekend and working on other days.
The apartment looks like on the pictures. Bedroom is small, but clean and nice. Almost everything is fine, apart from non-working microwave oven.
The location is quite close to the Aldgate station (~7 min walking). Also it's in the walking distance from the Tower and City area. On weekend nights it was a bit noisy outside due to some drunk guys passing by.

Overall - good value for money.
