We stayed at Uta's home for one month. It was really a great experience. Uta is a lovely person with a lovely house!.
It's a bright, spacious and very quiet apartment. 5 blocks from Old Street (northern line), various buses stop next to the building, walking distance to Shoreditch, a grocery and a supermarket just across the street.
The only missing detail... a TV to watch some movies...
Highly recommended!. We'd definitely come back!
