Don’t expect Marcel to communicate….at all. Make sure you have time to confirm your booking before you arrive, as this place and checkin- in, is always loaded with surprises. Read description well. The penthouse has a lot of steep and uncomfortable steps (like many classic Amsterdam buildings), so make sure you have someone strong enough to carry luggage if you bring any (these stairs are made for very tiny feet, maybe for elves or gnomes that first inhabited these grounds). Other than that, cool place to chill, no one bothers you.
