I had a wonderful stay of three months at Smillah's place and definitely recommend it!
The place is very cosy.
The room offers all that is needed, it is very practical with regards to traveller's requirements such as power plugs and storage space for clothing etc. The personal highlight of the room is the spacious rooftop window, which allows to quickly ventilate the room when getting back after a strenuous work day and, if opened fully, even allows to have phone conversations within it.
Shower and laundry (including iron) were always in a good condition and could be used any time, which allowed for minimal planning. I got a dedicated shelf in the fridge and, being a fan of gas stoves, also enjoyed the kitchen very much.
The garden is very nice and quiet - the perfect extension of the open living room when there is good weather.
Smillah is very welcoming and easy to talk with. She quickly introduced me in the basics of Danish culture as well as how to get around in Copenhagen.
In case you want to explore more than the city of Copenhagen as well as have a good rest at Smillah's home, there is a peaceful park connecting a lake 1.5km in the north to Valby park located at the sea 2km in the south. This offers great options for running.
