NanNa's place is super well located 15min walking from the main train station in Copenhagen and like 6 min from the metro. It's a great spot in the Vesterbro neighborhood, close to the nice restaurants in the meat packing district.
Space was clean and open, well appointed if you don't need a kitchen.
It is on the top floor of the building (no elevator) so be prepared for stairs. Also it's an older building so sound carries as well.
Overall a nice spot in Copenhagen!
