Marrigje's Waterhuis is a special garden oasis on the water, a quiet retreat from busy Amsterdam. We stayed there after 7 weeks of travel, and were able to just enjoy the garden, the quiet views, the easy 15 minute walk to Thuis aan de Amstel (definitely recommend this restaurant).
Both bedrooms were quite comfortable, and it was very handy having two bathrooms. Marrigje provided a generous setup of ham, cheese, bread, jam, eggs from her own chickens, juice, yogurt, and cereal, definitely a superhost! While we didn't use the bikes, there are many available for guests.
You will have to take a tram or ride a bike or take a taxi to get into downtown Amsterdam. We took the tram, it's easy, the station is about a 20 minute walk. We stayed in a downtown hotel for one night for two days of intense museum-going, then transferred to Marrigje's for blissful quiet time. Absolutely 5 stars!
