Location wise it's perfect. On the edge of Vondelpark, on the line of tram 5 (and others) which will take you right through town to Centraal Station, and within 5mins walk of Leidseplein. So it's a lot better than the previous hotel you asked about :0)
I haven't stayed there (having lived in Amsterdam and now living 40mins away, there isn't much need for me to do so) but I did check a couple of site with reviews from people who have stayed there previously
Apparently it has changed name to Hotel Blyss (which is a bit wierd to me!) and the reviews are really mixed so it is difficult to say. Perhaps it's best if you read them for yourself here so you can see
