Great apartment in a great location. Joanna´s place is near the tube (Angel and Highbury & Islington) and close to Upper Street where you can find lots of good restaurants and pubs.
The room was perfect (just like in the pictures!) and the bed was really comfortable.
Joanna is a nice and helpful host, she gave us good instructions to get the train to the airport!
I would recommend her place to stay in london!
