Although Dimitri wasn't there while we stayed at his place, he was very helpful and kind since we booked it. He gave us detailed instructions about everything (buses, directions, etc.) and even accepted us to check-in quite late on the first night.
The room is the same as on the pictures shown - big enough, with big bed, clean linen and towels and enough free space in the wardrobe for your belongings. The kitchen was also at our disposal, the bathroom was OK as well.
The neighborhood is calm and London's city center can be easily reached by the tube or by bus. Underground station is just 10 minutes walk, bus stops are pretty close and there are lots of supermarkets near Dimitri's place. For football fans, Emirates Stadium is also not far away.
We can fully recommend this place, as it was an integral part of our wonderful stay in London!
Thanks for everything, Dimitri!
