I had a great stay at Nienke's & Gert's bnb. The location is very quiet and a welcome respite from busy Amsterdam. The ferry is close by (12 minute walk) which takes you to Amsterdam Central station for free. Alternatively bus 35 is much closer, which also takes you to station central.
The room itself is quite comfortable with a nice bed, couch and tv. The private bathroom is also great and well supplied. Breakfast is prepared to order and introduced a nice variety in the form of different fruit across the 4 days I was there.
Nienke and Gert are very nice and they were available for any questions I had. I thought they were very accommodating. All in all, it was a great experience and I highly recommend their bnb.
