Superb location! It's super central and very close to the train station, Tivoli and loads more. We found it to be a very comfortable, clean flat that's beautifully decorated in true Scandinavian style.
The whole process is professional, organised and communication is easy.
If you can, try La Glace, Copenhagen's oldest pastry shop for amazing Danish confectionary. The Design Museum is fun, the canal tour at Nyhavn is a must as it's a great way to see Copenhagen and has some heating! We had really good glögg and æbleskiver (Danish doughnut style balls) at a waterfront cafe in Nyhavn and we loved Tivoli which was pure magic (although I have say that we were there outside of school holidays which made queuing a doddle). All in all, most places are really accessible because it's such a walkable city.
We totally recommend Hanna's flat.
