Everything about our stay in Tom's apartment was terrific! The photos in his listing are very accurate, but the space is even larger and more pleasant than we had imagined. The apartment is immaculately clean and very well provisioned, especially the kitchen (with cooking implements, cutlery, and dishes). The mattress is extremely comfortable.
The apartment is on the (American) second floor, up one typically-steep flight of steps. It has wonderful, bright light all day through large, perfectly spotless windows. The security arrangements, for those who worry about such things, are fine - multiple locks on the door. With one brief glitch (which Tom fixed quickly), the WiFi was strong and worked fine. We did not use the television.
Tom is friendly and welcoming. His communications are excellent and he was responsive to all of our questions. He met us in the apartment at a time we requested, soon after our morning arrival in Amsterdam, and showed us through, taking a generous amount of time to do so. When we had the problem with the WiFi and other questions, he responded in exactly the way you would hope, promptly and thoroughly, always following up with additional communications to make sure that everything was okay.
Re location: by looking at a map, the apartment might seem farther away from the center than one would ideally want, but in truth, its location just one block away from the tram line meant that we were able to get into the city center very quickly. (The #4 Tram appears frequently.) The neighborhood is full of neat, medium-sized residential apartment blocks characteristic of Amsterdam, and it is quite pleasant and very safe. The apartment's location affords a peaceful feel that seems "local" rather than "touristy." Having the well-stocked DEEN grocery store just a few steps from the front door made shopping a breeze, but additionally, the broad thoroughfare immediately to the east is a vibrant, local shopping street. There is a wide array of wonderful shops including a bakery, a wine and cheese shop, a florist, and much more. All of the shopkeepers - indeed, everyone we met, including local transit officials - were open, friendly and extremely gracious.
One more thing about the apartment's location: being near Station RAI (a 10-minute walk, or a 2-stop tram ride) meant that we were able to travel to other cities (e.g., the Hague, Delft) on day-trips with extreme ease.
