We stayed for 3 nights at Klaartje's. My husband and I had a wonderful time in this cozy and beautiful place. We did not use public transport, because we prefer walking as it was just 30 minutes walk to the city center! Although it was possible to get to the center by tram (go to a stop about 5 minutes). But a walk along the riverbank was more preferable for us.
Everything was fine, as we expected.
When we return to Amsterdam, we will obviously stop at this place again.
We certainly recommend this place and are very grateful to Klaartje for her hospitality.
