Jacques's apartment was wonderful. The Nyhavn location was the best in Copenhagen. The view was great and we loved opening the windows and little balcony to enjoy the sites water/sunset/sunrise, people/boats/bike riders. There were comfortable beds, two floors with 2 bedrooms, living room, Kitchen and dining room with a big table. There were two full bathrooms , washer and dryer all worked well (there was an additional 1/2 bath we didn't need or use). The apartment is close to some great bakery's with the most delicious danish treats. There are plenty of restaurants just below and all along the street. Metro was close but we walked almost everywhere. We also used the Hop on Hop off bus/boat to visit local sites of interest which was good for 72 hours if you pay for 24. The apartment is located on the 3rd/4th floor so you should be able to climb stairs with your luggage (the location and view are certainly worth the climb).
The communication / check-in was easy. We had an early flight and were able to check in early. Jacques explained how to take the metro and where to find the apartment. If you are visiting Copenhagen we highly recommend this apartment.
