If you are going to Copenhagen, I cannot imagine a better place to stay, for several reasons:
1) The flat is charming and "hygge" with everything you need to relax or play while in the city. Check our their wooden hopnotist. My 8-year old daughter and I were a little obsessed with it, so we got one of our own and a few more as gifts from the souvenir store down the street.
2) If you're staying in, there are great views from the window on the 3rd floor, especially if it's snowing, comfortable places to sit and relax, and fun music and lighting system to set the mood. There are also several places just downstairs to grab a bite to eat, or use Wolt or other type of food delivery service.
3) If you're going out, the flat is in a fantastic central location, a few minutes walk to city center, without being too close to busy hustle and bustle. We did not rent a car while we were there. We walked almost everywhere, except a day when we ventured to Helsingor and we took the train, which we could walk to the train station easily from the flat. We didn't get to for this trip due to COVID restrictions, but you can also take a ferry to Sweden from Helsingor.
Communication with Ani was great, especially when I discovered I left my phone in Denmark, even though I was heading back to the states! They worked with me to get that resolved as soon as possible.
I hope to come back to Denmark soon, and if we do, I will most certainly come back to this same flat! :)
