4 flights of narrow stairs, the last 2 flights are like "ladders" that you have to climb on all 4s like a dog... just to get through the "hole" without bumping your head.
Imagine "climbing" into a treehouse with a large suitcase. My wife is a very short 5ft2, and kept bumping her head... that's how small the "hole" is you have to climb through.
Shower water pressure is non-existent. Wife had to wash the soap out of her hair in the sink.
No heat..... at all. There are radiators, but no thermostat. The room has 2 tiny space heaters, one of which is broken.
The hairdryer is broken.
No couch.. just a couple hard chairs.
Plenty of "threats" about smoking in the room, but they are un-enforced. People below us hanging out the window 24/7 smoking, in plain view, stinking up our room. Couldn't open our windows when it was warm. 3 days straight, and no one did anything about it.
Not that we'd want to open the windows anyway, there is ZERO protection to keep your small children from falling out.
This isn't a "family loft suite". It's a poorly converted ATTIC that barely qualifies as a room, much less a "family suite".
I know many hotels in Amsterdam are converted old buildings. We've stayed there many times, at many places. This was not acceptable, by any standards.
Stay somewhere else with your family. You'll thank me later.
