we had a great stay, the flat was very nice and beyond. The balcony's huge and the room fully equipped. Although David was not there to welcome us (we arrived later than planned - so all on us) everything was ready for us and he guided us through over the phone.
In addition of everything the best thing about the flat is definitely the location, in a lovely quiet square yet 1min walk from all the Islington fun - and the balcony is huge
