Karina's place is wonderful. It's a great location -- it's only a five minute walk to the ferry that runs every few minutes 24/7 to Amsterdam Centraal. It felt like the more peaceful, residential side of Amsterdam that's not as busy but still plenty to do around.
The boathouse is a great unique home with a relaxing waterfront view. It has everything one would want -- it felt safe, it was clean, included all of the basic amenities, and it has a lot of character. The high bed made us feel like kids again. Would definitely recommend.
