We recently returned from our 4-night stay at Henning’s apartment in Amsterdam, which we highly recommend!
First, the apartment itself was great. Spotless upon our arrival, the apartment has a well-appointed living room, kitchen and bathroom on the ground floor, with a comfortable bed and nicely sized cabinet on the large top-floor loft. It’s just right for a couple looking for a nice place in the center of Amsterdam.
Second, the location is fantastic. The apartment is located on a quiet side street near the Vijzelgracht tram stop (~3-minute walk), where you can take the 16 or 24 tram lines to Amsterdam Centraal (~10-minute ride). Since the apartment is centrally located, we basically walked everywhere, and only took the trams from/to Amsterdam Centraal (~20-minute train ride from/to Schiphol Airport). For example, the apartment is close to the Heineken Experience (~7-minute walk), the Rijksmuseum (~10-minute walk), Albert Cuyp Market (~10-minute walk), Leidseplein (~15 minutes) and Dam Square (~20-minute walk). And there are plenty of restaurants to choose from in the area.
Third, Henning was a great host. He replied promptly to all our correspondence prior to our visit, was very friendly and helpful upon our arrival, and gave us some nice restaurant tips too.

In summary, the apartment, location and host were all great!
