My hotel stay was wonderful! I booked the loft. It was very spacious, clean, spacious, and well equipped - there was silverware, crockery, a nespresso machine, fridge, and microwave. I liked the continental breakfast that was brought to my room, and the staff were also very helpful.
I had to climb two flights of stairs to get to the door of the loft and then another one once inside the room, but I was very glad for the exercise. Just be aware of this and book a room on the ground or second floor (first floor outside the US) if you don't find stairs convenient.
If I'm ever in Leiden again, I will definitely stay here. 10/10!
