O&V are amazing hosts. They sent us detailed information about how to get to the place, were accommodating with check-in, check-out and helped us with tips about the city. They are a very warm couple always open to engage with their guests and help out. The flat itself is very stylish, at the top of a traditional house and the room was super clean. It is located only 10 minutes (on foot) away from the center and next to the Museumquarter with nice bars and restaurants around.
