Stayed in Karlijn's apartment for 2 weeks, one vacation and one work. Her apartment is just as described - very nice, and actually larger than we expected. The bedroom is in the back of the apartment, which made for nice, quiet sleep with no street noise. The location is great too - quick walk to trams, cafes, and restaurants!
Karlijn is a great host! She waited for us at the apartment when we arrived, walked us through everything we needed to know, and checked in several times to make sure everything was going well.
We had no issues during our stay, and would absolutely stay there again when we're in Amsterdam. Thanks Karlijn!
