Antony's flat is located right next to the London Overground, Hampstead Heath, and a few minutes from the bus and tube, so you're spoiled for choice getting around.
The flat itself was secure, spotless, with a big TV, comfortable bed, good WiFi and everything you could need for a short or extended stay. Antony was responsive and provided detailed instructions on how to pick up the key and how to use the various items within the flat. Note that the flat is at the top of a narrow set of stairs if you're carrying a lot of luggage.
Highly recommended, and I'd happily stay here again :)
