Stef and his wife are utterly nice people, we enjoyed our stay at their apartment a lot. The room itself is very cozy, you immediately feel at home, as though you have spent all your life there. The beds are comfortable, the terrace is gorgeous, and delicious cookies are resupplied every day. It is a bit far from the center if you go on foot, but the public transport communication is convenient, even at night. We definitely recommend this place to stay in Amsterdam.
