We've spent 2 nights at intell city centre. It was joint birthday trip. We arrived just after 9 am and got checked in immediately which was amazing. We requested quiet room and got one on the top floor overlooking courtyard/breakfast room. Decor is a bit dated (textured painted wallpaper) but that's about it on the downside. 5 mins after check in we got a knock on the door and got a birthday surprise from the hotel. Happy again.
Everything spotless, staff extremely helpfull, made several suggestions that turned out to be great even though we've been to amsterdam several times before.
Obviously location is great. Breakfast plentiful with fresh juice and even bubbly if you feel like it. King size bed comfy.
