Martin and Jan are young guys who are looking to meet cool people. They're friendly, fun, and courteous, and are just as happy to go out with you for a drink or food as they are to just leave you alone if you want peace and quiet. They gave great tips and recommendations for things to do, and were helpful with planning of activities.
The apartment itself is large, reasonably priced for what you get, and fairly clean. Good location, no outside noise from the street, and east access to food/bars/public transportation.
