I'd recommend Klaas' apartment to absolutely anyone wanting to visit Amsterdam. Perfect location directly next to the tram and extremely clean and comfortable living space. Couldn't have asked for more. Klaas and his son were very kind, welcoming, and ready to answer any questions we had about getting around the area. The beds were so comfortable, bathrooms clean, extra towels if we needed them, coffee machine and sink in our room, helpful brochures/maps ready for us at our convenience, and a fridge to store food if need be. Klaas also allowed us to keep our bags at his place past check out time so that we didn't have to drag them around the city while we awaited our departure later on in the day. Very grateful to Klaas and his family for welcoming us into his wonderful place!
