I know nothing about the hotel but it looks like its in a pretty central location.
Personally, I don't like going into Amsterdam. There's too many tourists (this is actually become a big thing, Amsterdam is trying to get tourists to go to other places in the country). I think most people can see and do everything that's worthwhile to do in about 3 days. The big museums like the Rijks, Van Gogh, and Rembrandthuis. Artis zoo. Some coffee shops (I know a place that makes space cakes that are home made and probably the best in the city).
If you're coming between March 21st and May 10th I do highly recommend getting out of the city and go to the Keukenhof gardens (the famous gardens with all the tulips). If you go during the week it's usually a little less crowded and there's buses going from Amsterdam directly to the Keukenhof.
April 27th you'll have Kings Day which is an interesting day to be in the city. All public transport shuts down and you're pretty much squashed between the drunk and high masses in orange.
If you like escape rooms, the city is infested with them now.
Also, consider this. I think it's a pretty good deal if you're planning on utilizing public transport and going to a bunch of museums.
