Excellent place for cat lovers. The mornings on the terrace with visits from the neighborhood cats where some of our favorite memories of our trip to Amsterdam. Even in October, it was lovely to spend time out there, because it was sunny and usually warm during the day time.
The location is great. Right across the street from the tram and a ~20 minute ride / 30 minute walk to central Amsterdam. But there are plenty of bars, restaurants and breakfast spots in the local neighborhood, not to mention how close the flat is to the Vondelpark. And the park is well lit and very safe even at night.
Har and Hank are very accommodating hosts. After I booked, Har quickly sent travel and check-in instructions. Don't worry about carrying heavy suitcases up the steep stairs--they took care of all of that for us. There was wine and flowers on the table when we arrived and beer in the fridge. The kitchenette has a kettle and a toaster. The shower was hot and easy to set a consistent temperature, but the rest of the water in the flat was cold.
We liked the comfortable bed and large windows. Everything in the flat has a sort of quirky, old century charm, so if you're looking for the most modern amenities, this place isn't for you. You can definitely hear other people moving about the old house, so pack earplugs if you're a light sleeper. With Dutch airbnb laws, we couldn't keep our bedroom door locked when we went out, which was a bit strange, but I always felt that our stuff was safe and secure. (There is an inside lock that you can latch at night.) It was dark and cozy at in the evenings, with dim lighting, and the bathroom is definitely not luxurious or spacious. The bathroom was not as clean as I would have liked it to be, but mostly due to the older fixtures and general dampness of the space, not filth or anything offensive. There were many towels provided and two very comfy bathrobes.
Overall, it's a good space for the money, and if you're looking to stay in an authentic 19th century house in a great neighborhood a bit outside of the tourist central spaces, I'd recommend it to you.
