Getting from Kristina’s place to Amsterdam Central Station was very easy with the bikes she let us use. It took about 20 minutes to get there by bike & ferry but we were biking very slowly. The room was nice and secluded, very quiet at night, and seemed to be completely separate from the rest of the house. The stairs are very steep so if you have heavy luggage this might be a problem for you, however we were able to manage. It was also nice to have breakfast and free parking on the street :).
