Lotte was a fantastic host. We followed most of her recommendations and they were all fantastic - she clearly knows the city really well. Follow her advice and bring slippers, the floor is beautiful hardwood but it does splinter a bit.
Location is perfect. You're a 10 minute walk from Tivoli gardens, a 20-30 minute walk from the harbour and 5 minutes from the main shopping area.
We went with our 1 year old, who loved all the toys. it was a bit of an effort getting the pram up the stairs (no lift) and it was a little noisy. We brought our own blackout blind, which is recommend if you have young kids who struggle to sleep with lights on
