Hannah's lovely home is about 3 minutes walk from Vanløse Metro station - passing a supermarket on the way for food supplies. Vanløse Metro is just 30 mins from the airport (opposite end of the line) and about 15 mins from the centre, with the Metro running 24/7. The Metro is really regular - roughly every 4 mins, in daytime at least. It's so easy to get around Copenhagen.
Hannah was a welcoming host; helpful when needed, but I also felt I had my own space and wasn't intruding on family life by being there. The apartment has real charm, and the bedroom is very comfortable. No problem at all to store some food in the fridge and make the odd meal during my stay, although I was out most of the time.
I wouldn't hesitate to recommend this as somewhere to stay, or to return here. Even if your aim is primarily to visit central Copenhagen, this is still a great location. I was attending an event in the Vanløse area, but still found it really easy to fit in sightseeing in the centre of Copenhagen at either end of the day because the transport links are so good.
Last but not least, it was lovely to be staying in a local's home - a far better way to get a flavour of a city than staying in a hotel or hostel. It felt wonderfully Danish!
