The host spoke perfect English. The apartment isn`t in central Copenhagen but is situated on a picturesque canal half-way between two metro stops so you can be in the city within ten or fifteen minutes. It is just across the boulevard from the Bella Centre which is a major convention centre (our reason for choosing the place). Also a couple of blocks to the south there is a train station that connects to the downtown train station in one direction and the airport (less than fifteen minutes) and on to Malmo across the bridge in Sweden in the other. Next to the station is a giant shopping complex, reportedly the largest in Scandinavia so you can get anything you might want at a reasonable price.
The apartment itself is bright and airy and amazingly has large windows facing opposite directions (there are three floors) so you can look out on whatever is going on in this relatively tranquil neighbourhood. We had the bottom floor to ourselves with direct access to the modern clean bathroom.
The host was ready with information and advice about what to visit. For example we found a place to eat in a newly developed market near the Norreport metro station that we wouldn`t have known about otherwise and although it was across the other side of central Copenhagen from where we were staying thanks to the excellent metro system we were back home in half an hour.
One word of warning, always bring an umbrella and sweater when visiting Denmark because although we did experience several days of hot and sunny weather we also had some when it drizzled and was absolutely chilly considering that we were there in the middle of July.
Altogether, the host and the apartment were perfect and its location with simple direct access to the airport at the beginning and end of our visit made it ideal.
