We were 2 couples and spent 2 nights there. We arrived at 0800 in the morning and since they had a room available, we were allowed to check in early. THAT was nice and unusual in our experience.
The hotel is more than one building. To reach our room , we had to take an elevator up a floor, walk down a hallway (a pedestrian corridor above the street), take a second elevator and walk to our room. Not a problem for us but it could be if you had a lot of baggage or had difficulty walking.
Room had a terrific view of the nearby rooftops; we had the window open and there was virtually no noise whatsoever. Room size is average by European standards and certainly adequate.
Beds were comfortable. Bathroom was large and luxurious. In room electric kettle so you could make coffee and tea. Wi fi worked fine, both in the room and in the lobby. There is also an in-room safe.
Breakfast was a hot and cold buffet - very good. What stands out is that you were able to make your own fresh squeezed orange juice.
Inntel is centrally located; within walking distance of the train station. It could be difficult to find as it is on a side street; so get good directions before you arrive and do not assume your taxi driver (if you needed one) will know where it is.
I would recommend the Inntel Amsterdam!
