I'm giving this place the five star because it was exactly what I expected in most ways, and exceeded my expectations in other ways.
To start with, the location couldn't be beat. It far exceeded my expectations.
After getting to Copenhapergen and seeing where the hotels actually were, I was so happy that I had booked this place. It would have been a completely different experience.
His apartment is perfectly located on a pedestrian only street just a block south of the Stroget and a block north of the Gammel Strand. There are cafes and restaurants right outside the front door, but because his apartment is the back of the building, there is no street noise and it's very quiet. We were in the middle of everything and equidistant from Tivoli area and Nyhavn.
And while the rest of the place met my expectations and I was happy with my stay, I have to point out that the building is very old. The floors creak and you have to be a conscious of making too much noise as you move around. You can hear your neighbors move (though, they didn't seem to move all that much). The bathroom is really, really small. The sink digs into your side while your sitting on the pot kind of small.
For us, it was three nights, and none of that mattered as the location trumped everything and I wouldn't hesitate to stay there again.
