This is a very comfortable apartment in a central area of Copenhagen: it is at 5 minutes walk from Nihavn and the same from the M2 station. At the same time it is very silent and you can sleep very well, without being disturbed by the traffic.
The sofa is not a sofa-bed, and we were quite skeptical about that; however, it was absolutely not a problem for our 163cm high daughter to sleep very well in it.
The apartment is at the 4th floor without elevator, and we were warned about that: for us it was not a problem, but it must be considered.
Very positive experience!
