Perfect Copenhagen stay! We only stayed for one night, but as the location was so central we managed to get loads done!
We got a taxi to and from the airport, which was easy (taxi rank at the airport and taxi phone/app from flat). The metro is also comfortably walkable, but you might struggle with heavy suitcases (we had six...).
Ruth has written a detailed guidebook to help you navigate the amazing food around the city. Our breakfast (Danish) pastries and coffee at the bakery on the corner were amazing.
Tivoli Gardens is a short 10-minute walk and well worth a visit - you could easily spend a whole day (and night) there.
Our flat was spacious and well maintained. Perfectly usable kitchen and a living room with a dining table. Brilliant shower!
The twin room connects to the rest of the flat through the double room, which was not an issue for us, but might not be ideal for others. The single room connects directly to the living room.
Ruth was very accommodating and was very quick with communication. I would definitely recommend it!
