We're renting out our lovely Østerbro apartment, situated on Rosenvængets alle - an old copple-stone street with great shops and restaurants. The flat has 2 bedrooms, 3 living rooms and a private roof terrace with views all over Copenhagen.
No particular rules apply over and above general decency. It's a family building with kids on all floors so rock and roll after 10.00 on a school night is not ideal. We also prefer no smoking, but the roof terrace provides all the space you need for a quite cigarette, cigar or pipe.
