This was our first time using AirBnB and thank goodness it was a very positive experience! Everything from the check in process, the grocery loaded fridge/well stocked kitchen, the clean, bright, spacious and functional apartment, and the apartment's location was excellent. This comes from a very picky family (we had our parents with us along with our 1.5 year old baby) as well...
The location is very close to Tivoli Gardens, and is flanked by several grocery stores - high end, lower end, asian, etc. It took us 15 mins to talk to Copenhagen City Hall where we took a free walking tour.
The apartment is equipped with a good elevator and once we checked in, we were so happy with the spacious nature of apartment. With all the windows it was nice and bright, and the kitchen and all rooms were well equipped.
Cettina did an amazing job getting us situated, with lots of tips and guidance for us. There was milk, juice, cheese, fruits, bread/pastry, coffee...etc. Food in copenhagen is not cheap compared to other cities so not having to pay 50 DKK (approx $10 Canadian) because we made our own delicious coffee at the apartment was nice.
We needed the two bedrooms and two bathrooms because we travelled with our parents. It was nice to have our own bathroom and not have to share, especially with our baby.
The place was also very well cleaned.
Make sure you learn how to use the convection oven with the right pots if you don't have this experience (we have a gas burner stove at home) or there might be some initial frustration.
Enjoy your stay -this was truly a sanctuary for us during a long trip through Europe.
