We loved Hotel Not Hotel! When we arrived in the morning, our room was not quite ready, but because the hotel was not full, they were able to upgrade us to a slightly larger room for the duration of our stay, at no additional cost. The room was extremely clean and refreshed daily. The shower was large and modern. And the bed was plush and comfortable. While there was no window to the outdoors, there was a window overlooking the shared living space, which had plenty of natural light during the day (we kept the curtain drawn though because when open, other guests can see into the room). The owners/staff were always friendly and accommodating, and made us feel right at home. We loved the location because it was far enough from the touristy areas, but easy to get everywhere via tram. The room is basically a crash spot for sleeping, but as beautiful as Amsterdam is, there's no reason to be in a hotel room for long. We would stay here again.
