Antonia is a very friendly and helpful host. The apartment is exactly as described, about 45 minutes to the center. The closest station is Willesden Junction, from there you got a direct line to Piccadilly Circus and many other important stations. From the airport Gatwick it takes you a bit more than an hour, depending on which train you catch. The heating system is in control of the host, it can get very cold during the night, so don't hesitate to contact Antonia if you need it warmer. The provided bed sheets and towels are very clean. We had a good time staying at this apartment.
