My gf and I stayed here for 4 nights, and it was fantastic! Astrid is a wonderful, gracious host, full of advice about Amsterdam and how to get around. Although on the map it looks like it's further out than some other accommodations, it is easy to get to the historic part of the city by walking through Vondelpark or just taking an easy trip on the #2 tram from the stop around the corner from the house.
The house itself is a converted garden cottage, and it is super clean and nice, pristinely furnished and cared for - much better and not to mention bigger than most hotel space you will find in Europe, at this or any price. I paid around 2x this price in Paris for something far less nice, much smaller, and less secluded/secure.
So easy to get to the airport - so easy to get downtown. The breakfast is delicious. She serves it herself and *encourages* you to take any leftovers with you for lunch. And there will be leftovers. She'll even provide you a plastic bag. Most hotels would, at best, frown on this practice, and at worst, publicly shame you. But Astrid knows what's up! She will even do her best to provide according to your wishes. But let her surprise you. The breakfast she brings is wonderful!
Toiletries? shampoo? Hairdryer? All there for your use.
Maps, books about Amsterdam and the Netherlands? Fully at your disposal?
TV with sat/cable? Check. Watch Jersey Shore with Dutch subtitles! (Fun for language nerds!)
Besides staying here, I cannot stress how great the Holland Pass is. Buy it from Expedia, print the voucher, and redeem at any Travelex, including right outside the trains at Centraal. Use the coupon to get 24 or 48 hours of free transit. We got the 7-event pass, and it more than paid for itself after only cashing in the transit coupon and going to three high-value "tulip ticket" events. The discount book also works at many more restaurants than you'd imagine. Don't forget to use it!
We had a great trip to Amsterdam, and Astrid and the Holland Pass were largely responsible. You will not be sorry you stayed here! Pet Flores and Puck for us!
