This has got to be the best place to stay in Amsterdam! It's very close to everything, yet the street feels private and away from the hustle and bustle. The neighborhood is beautiful, and there are cafes, bakeries, bars, and excellent restaurants (we loved d'Rigeour just a few doors down, not sure if I'm spelling the name right) within a couple blocks.
The apartment itself is very clean, comfortable, well-decorated, and very thoughtfully kept. It has everything you need: cool decor, guide books and local recommendations, nice bathroom and shower, plenty of natural light but heavy curtains to keep it dark so you can sleep in, table and chairs, tv, and a little kitchenette with fridge, sink, dishes and utensils, and coffee and tea amenities. We stayed here with our one-year-old and it was perfect.
Ad and Anna are responsive, friendly, and helpful. They even brought us some local treats to taste! Highly recommend staying here if you have the chance!
