This is the perfect place for two couples or a family. We loved the layout and design, and ended up staying in and cooking more than expected because the house is so beautiful and the fully stocked kitchen had all the equipment we needed, with many markets nearby. The house is historic, beautiful, and ideally located just between the Jordaan and Nine Streets districts. It's a gorgeous part of the city.
Be aware that the stairs really are exceptionally steep due to the nature of the house, and street noise and sunlight might pose issues for some travelers (I just wore ear plugs and used a sleep mask and was fine, but those in our party who weren't comfortable with ear plugs didn't sleep well). This is a gem of a house, we loved our stay, but it's not for everyone.
But my goodness, what a find! Loved it and recommend it highly with only a few caveats (stairs and street noise) that are not the fault of management. Overall this is a wonderful house that is extremely well cared for, and a beautiful, interesting, and unique choice for Amsterdam accommodations.
