Me and two girlfriends stayed in Sofie's flat for three nights while exploring Copenhagen and we all had a lovely time. The flat is very cosy, clean, with a lovely kitchen and everything needed for a good stay. There were three of us but Sofie had prepared a nice (and comfy) extra bed on the floor and coffee! She also left a list of things to do in Copenhagen, sadly we did not have time to do even half!
The flat is a bit far from the city centre, but it is close to local busses, and if the weather is nice the walk to the botanical gardens did not take too long. Two small grocery stores in the same block and it was a nice, quiet area. Would definitely recommend!
