Our stay at Paul's apartment was great and we definitely recommend a stay there. It was very clean and like on the photos. (There was no frying pan which was not a problem for us but if you plan to cook this might be good to know.) It is at the ground floor but there are plissées and curtains so no one can look inside. There was very few traffic in the street although it is very centrally located with a lot of restaurants etc. nearby. The location is perfect for a city trip: It is not that crowded as directly in the city center and less noisy. However, you can visit a lot in walking distance. Also the metro and tram are nearby and only take some minutes to the center.
Paul was very communicative and supportive. He gave us a lot of tips on what to visit, where to eat, how to travel and how to get to the apartment. This was really helpful. Also the check-in and check-out were perfect and uncomplicated. Definitely recommended if you like to visit Amsterdam :-).
