We had a wonderful time in Cornelia's flat.
The flat is charming, very clean, and perfectly decorated. And, the location is AMAZING! It is steps away from Tivoli, Central Station, the main pedestrian shopping area, and tons of restaurants and pubs. Because it is in the center of town, it can be noisy with the windows open - but what do you expect in the center of town?
Cornelia is a wonderful host. She responded to every communication very quickly. Our flight was delayed, so we had to change our arrival schedule (an inconvenience to her), and she did not complain one bit. She provided recommendations for restaurants and even suggested places to avoid - a big help!
In summary, the flat is VERY charming and perfectly located in the center of the action, and Cornelia is a wonderful host!
