I cant say about what your experience will be (or have been ) but mine experience has been excellent!
Firstly, the location. Its not far outside of Amsterdam central. If you are looking for somewhere calm for a large group away from the busyness of the central, this is definitely worth a look. The Metro ( GVB) is just a mere 5 minutes walk away and itself is a 20 minute ride away from Amsterdam Centraal. The apartment itself is located beside some canals so you do got some nice views of it.
Secondly, Niloufar and her mother, Corrine has been a really great host to our family of 6. We arrived early in the morning and Niloufar allowed us to check in early so that we would not have to lug our bags around Amsterdam. Niloufar was not present for the check in but in her stead is her mother, Corrine and she is also a lovely person to meet. We felt the hospitality the moment we stepped into the house. Both of them made sure that we were settled in fine. On our last day, they even allowed for us to leave the luggage in the property so we could do a last round of sightseeing in Amsterdam ( mind you we have already supposed to check out ). I was touched and pleased by this as they have gone above and beyond to make our stay the best it can . Corrine even gave us a bag of goodies!
Thirdly, the place itself is immaculate. Modern and chic apartment suitable for a group of friends or a family. 3 bedrooms, a spacious living and kitchen area and nice balcony area for you to relax on a warm day outside. The apartment itself is equipped with amenities; it is also quite large. You would have to experience it yourself to know how good it is!
10/10 would recommend !
