We really enjoyed our week's stay in Nanna's home. We were travelling with our two year old toddlers and the apartment was perfect for us. Our children were able to play with the toys in the apartment, pick raspberries in the private fenced garden and enjoy the communal playground and garden shared with the other apartments in the complex. There were also two public playgrounds less than 50m away. Toddler (and parent) paradise! We were able to park our pram in the complex's designated pram room a few metres from the back door of the apartment.
As others have noted there is no washing machine in the apartment, and the toilet and shower are small but functional. None of this was an issue for us. There is a laundromat close by if you need to do laundry.
The location was great- very close to a bus line with buses heading to/from the city every few minutes, and walking distance to a variety of shops and restaurants. Norrebro is a very interesting multicultural suburb and worth exploring.
To sum up: we would definitely like to stay at Nanna's place again next time we are in CPH.
