We stayed in Sheryl & Lukasz's apartment for 3 nights and definitely enjoyed our stay here. You do have to climb 3 flight of stairs to reach the apartment but once you're there you will be greeted with a cool apartment with hip architectural design yet still very homey. We were greeted by Sheryl herself who was lovely and showed us around her apartment. We also loved the area as it felt safe and was closed to cafe's, restaurants as well close to public transport. We have no qualms recommending the house to anyone coming to Amsterdam!
