The apartment was everything we expected and more. It was clean, big enough for the two of us, it is very well equipped, in a very quiet neighborhood, but still close to the supermarket and the best part: 3 minutes walk from two great tube lines, the District and the Piccadilly.
The communication with Tim was very good and he even sent us the keys to the apartment in advance so we will have no problem with the very late check-in (midnight).
The apartment even has a small balcony which was a great place for an afternoon beer just before heading again to the evening activities
