The apartment is close to the Amsterdam centraal station as well as the Anne Frank House. Supermarkets and nice restaurants are also in close proximity.
Apartment is spacious and clean with all amenities working fine. Niels is friendly to us during check in and he is very approachable when we had any questions. We ran into some washing machine issues at night and help is nearby as the owner is just staying in the unit above.
We stayed in the apartment in June and there's absolutely no need for the air condition as the place is cooling enough.
Will recommend our friends to stay at Niels' place when they are in Amsterdam!
