We stayed in two rooms, on two separate stays. The first was the top floor, and it was great -- a large comfortable room, wonderful natural light from expansive windows overlooking the back gardens of the neighboring traditional Amsterdam houses. This room opens onto the shared living room with kitchen and dining facilities, comfortable sofa and chairs, and guest computer. The room is quite a hike up the steep stairs, but with Jasper's help, we managed to get the bags into the room with no difficulty.
As others have said, Jasper is simply the most welcoming, helpful, kind and generous host one could imagine. Generous with his time and information, as well as generous with those amazing breakfasts. We were there during Queen's day, 2013 -- which in this case meant the inauguration of the new king. We awoke to the sound of the cannons saluting the new king, and then wandered into the living room area for coffee. Jasper had set out breakfast things, but also orange paper crowns so we could immediately get into the swing of things. He soon arrived to help translate the non-stop TV broadcast of the festivities, so we would understand what was going on. He told us the best places to go to get into the fun of the day .... as well as what to avoid and when to call it quits. He as just terrific.
We found the location a real plus. The neighborhood is quiet and clean, and nearby trams deliver you quickly to any of the center city attractions.
We stayed in another room for one night, when we returned to Amsterdam after several weeks of touring. This room was down one level, also at the back of the house, and equally comfortable and welcoming. Jasper made sure we had coffee, fruit, bread, eggs and other necessities to munch on as we dressed early in the morning before leaving to catch our plane home. And he was there to help welcome our taxi, and to help get our bags down the stairs. He is simply the best innkeeper we've ever run into, and we felt so fortunate to be able to stay in this wonderful place.
