Thanos was very helpful, flexible and prompt to answer all the questions we had before our stay. He allows ut to leave our luggages after normal check-out time.
The flat is well located with 2 metro stations 3 mn walking ( perfect for marathon runners.... ), bus stops to central London very close too. Very quiet street, with plenty of restaurants around.
We were 2 couples and the flat is just perfect with 2 bathrooms, kitchen with all we can need, and beds very confortable.
I will really recommend Thanos's flat and will come back there with great pleasure.
