The location of the apartment is perfect, in close proximity to central station/metro. We actually walked to most attractions/sights. Lidl supermarket also nearby.
The apartment itself is beautiful and provides everything you could possibly want for a short get away. Check-in was simple and easy, we arrived early but reception rang us as soon as our apartment was ready, which was before the check-in time. Reception also helped arrange a taxi for us in the evening.
Only one negative, which I know is not directly the hosts fault, but it did affect our stay. An apartment which overlooks the courtyard is having some sort of building work. We were woken every morning at approx. 7am from the noise which isn’t ideal when your trying to relax on holiday. If this is going to be long term, I suggest they inform people prior to their arrival. However, I would stay at the apartment if I were to visit Copenhagen again.
