I live in Sydenham in a three bedroom flat with my 15 year old son. I have a cosy double bedroom to rent for one person or a couple. We're right in front of Wells Park, near the Horniman Museum.
Sydenham is the nearest Station (overground, zone 3): 15 MINUTES WALK or 6 min bus ride.
Trains from Sydenham Station take 20 minutes to London Bridge, easy connection to Central London.
Another option is Sydenham Hill Station (railways) also 15 minutes walk, with trains to Victoria Station.
