We had a great time at Lotte's flat! It is in a wonderful location, very close to Meyers Deli and Rist coffee shop which are two of my favourite spots for bread / pastries and coffee in Copenhagen. Also, we walked everywhere and never went on public transport. It only takes you 15 minutes to Central Station and city center which I thought it was great.
The flat itself is cosy and pretty. They have amazing cooking books in the flat which were nice to look at. The flat was warm enough and had no problems whatsoever. I definitely recommend it!
