We loved this place and this neighborhood.
The flat is beautiful and comfortable, and easy to access public transport or bike rentals. It's on the top (4th) floor of the building and is a walk-up (which is the case for the majority of homes in CPH), so the elderly or those with disabilities should consider this for any place in CPH. Similarly, the bathroom and shower are smaller. We ourselves had no problem with this; just FYI.
The neighborhood is wonderful and lively, with many amazing coffee shops, restaurants, parks, and boutiques nearby.
The hosts sent us a lengthy and very thoughtful list of recommendations in the neighborhood and beyond. They were very responsive to messages/questions.
We would not hesitate to stay here again or recommend this place to others. Enjoy!
