4 room apartment in Frederiksberg

It is a lovely 4-room apartment of 95 sqm with good transport options nearby. The rent is approx. DKK 9,000 per month, including an advance payment for heating. The apartment is on the 2nd floor with an elevator and has a balcony. I wish to swap for a larger home — preferably a townhouse or an apartment — of at least 120 sqm and at least 5 rooms. If it is an apartment, there must be a balcony and an elevator. I am open to homes in the following areas: Frederiksberg, Glostrup, Hvidovre, Rødovre, Østerbro, Gentofte, and Hellerup.
