My stay in Will's apartment was simply perfect.
Will replied my messages immediately since the beginning and was very kind in every moment.
It is a modern, very new, clean and well equipped apartment. The room is bright and comfortable.
It is located in a quiet neighbourhood, almost one hour by train or bus from Central London. Train station is ten minutes far walking, and you can take buses from the train station also, three stops only. This is not a long distance into a very big city like London, and the price is excelent, maybe the best related to comfort.
In summary: I will book again Will's apartment when I will come back to London my next time, no doubt!
