We stayed for one week in this apartment, and it was plenty of space for four adults. The furnishings are colorful and comfortable, the rooms are filled with light when the blinds are up, and the view of the garden is lovely. It is in a quiet neighborhood with rolling hills, good for walking and biking, and relatively close to a grocery store and restaurants.
This was the layout when we stayed (a little different from the pictures, but not in a bad way): The entrance leads straight into the living room, which also has a dining table that seats six. Through the living room, immediately to the left is the bathroom and to the right a hallway with a coat closet and another small table. Off the hallway is the first bedroom, which has two beds (queen and twin) and a dresser. The hallway leads into the kitchen, and to its right is the second bedroom, which has a king bed, desk, and armoire. The layout is convenient, and it is possible to close doors to the living room and kitchen to stop noise from traveling to other rooms.
The Hübels are such a sweet family, and the apartment is everything you could ask. We highly recommend staying here!
