We had a very pleasant stay at this lovely place. The location is the best in the city. The host is very responsive and flexible. Highly recommended.
The apt is on the 3rd floor, and there is actually an elevator which was quite convenient for us to bring luggage up/down.
If you will sleep in the extra bed in the living room, the window does have blackout shades, but the door leading to the balcony does not. It did not bother our sleep while we stayed there because the sun is up quite late in Dec in Copenhagen.
