Rasmus' place is, primarily, superbly located to explore Copenhagen and is in walking/bussing distance from nearly everything. You can be there in far less than an hour from the airport, using just public transport.
The flat is cosy and compact. I would say it is perhaps a space suited to a younger couple (as a host myself I find older couples tend to be far more demanding....). It's certainly not a show flat, but it has a nice, chilled vibe.
The area is very quiet considering how close you are to the centre. Almost startlingly so. There are a lot of flights of steps, so if you are of limited mobility be aware. The bed is also quite firm!
Rasmus was very flexible on check in and out, which we appreciated.
I think I might be addicted to the chicken sticks from the local Seven Eleven so might need to go back soon....
Overall we had a great time in Copenhagen.
