Cityden was a great location. I didn't realize at the time, but it is actually a hotel that lists room on airBnb, so if you are trying to avoid hotels, be warned now.
That being said, the entire staff was very courteous. It was nice to have access to clean towels and blankets at the 24 hour desk. There's also a little convenient store as well that was very useful.
The airBnb is a little further out of the city center, but there was both a tram and bus stop within a few minutes of walking. The public transit is great in Amsterdam so we were able to use that to get around very easily.
It was great experience! We all enjoyed our stay at Cityden and Amsterdam!
