Location, location, location - you could not get a better place to stay in Amsterdam.
Kiek and Eiso are excellent hosts and it is great that they actually meet you and share information.
I have no hesitation in recommending this accommodation- but be aware that it is in a Basement and the ceiling height would be an issue for anyone over 5ft 7in - but to stay in a building built in the late 1500’s - amazing!!!!
