The apartment is much smaller than we imagined. If you don't mind bumping elbows on every aspect of the room and you don't mind sacrificing space then this is ok for you. The kitchen area is tiny the sink is too small to wash pots and pans after you have cooked. The shower is very oddly shaped if you are more than 5ft 10 you can't shower standing up straight.
The walk to forest hill overground station is 12 - 15 mins with very steep hills to walk both there and back. The distance to central London is about 30 mins of travel and change overs depending on where you want to go.
Although this is not a bad reflection on our hosts nor their fault, it is important to mention there was a theft of my laptop and passports from my car parked outside their property.
