As others have said, the location was excellent and easy to get to by metro. although busy during the day Nyhaven doesn't seem to have late bars and except for one night it'squiet during the night. You can get everywhere by foot from this location and Copenhagen is a lovely city.
Tip, if looking for a nice restaurant book in advance.
The apartment was a good size, well decorated and has a nice bathroom. communications from the managers are prompt but not necessarily acted upon. it is owned and run by a restaurant chain.
Negatives....
The smell of grease from the restaurant is really strong. The extraction fan is located in a side storeroom of the apartment. You get used to it, but our eyes were stinging on night one and our clothes really smelt of grease when we got home.
Check in information was slow to come and we also started to think it may be a scam because we had to chase for them. the entrance was hard to find from the information provided.
The facilities were sparse. Although a coffee pod machine is there. We felt we were missing a microwave, tea facilites, and there was no welcome/starter pack or information folder.
This is the first Airbnb I've stayed at without and iron and ironing board. We were told an iron would be delivered but it never arrived. There were also no clothes hangers.
We were allowed to keep our bags I. the apartment for a few hours after check out which was really helpful.
