Hotel Nadia was a great choice. I was a bit apprehensive when I arrived since it was a two star, but was pleasantly surprised. The hotel was clean and the staff was friendly. Breakfast was typical for Europe, but got us through until lunch. The hotel is located near the great sites, about 1/4 mile , maybe a bit more to the Anne Frank House, and about 5 minutes to the Palace. We used the Car Hotel service (not affiliated with Hotel Nadia). It was only 50 Euro for 2 nights, and picked up the car at the curb. There was a bit of a wait until they arrived, but the easiest thing to do. If you are looking for an inexpensive clean hotel near the main sites this is a good choice.
