i can only agree to the positive feedback on here: my stay at caroline's place was superb - i felt like a flatmate rather than someone who has rented a room. the communication has has been very good and the room and house is as described.
i liked the area (hardly any tourists but many good cafes and a neighbourhood-vibe) and you can easily explore hackney/dalston and even shoreditch by foot if you like but a bus can take you pretty much everywhere, too. (bus stops are super close as well as trains/overground in short walking distance). overall i would love to come back for my next visit.
