Very close to New Cross Gate Station for easy access by Overground and regional trains. The area is well serviced by busses too. Plenty of local shops and cafes in walking distance. (There's a Sainsbury's next to the train station.) It's off the main road in a quiet residential area. Lovely modern kitchen and lounge/conservatory to relax in.
Just a note if you're a light sleeper: New Cross is under the eastern approach path to Heathrow Airport if planes are landing from the east. It wasn't an issue for us as we sleep like the dead...
