The place is a great spot not only for a family trip (very close to Kierkegaard park and the green path) also perfect for a trip with friends (great location between the beautiful Frederiksberg and Nørrebro - a district full of small cafes and pubs). The place away from tourists and walking distance to center of town (around 15mins).
The flat is very cozy, sunny with balcony where you can relax. There are 3 rooms (2 bedrooms) with well equipped kitchen. If you are lucky you can can get a welcome beer ;)
Contact with Lasse was very good, he had no trouble to welcome me with friends and a small baby. I would definitely recommend this apartment.
