Well, everyone else has already said it. Be prepared to do a lot of climbing. If you have some aversion to physical activity, or if you are unable to do so, this might not be the flat for you. However, it's worth it. The said staircase also happens to be beautiful, and the studio at the top is too. The kitchen is fully equipped, the bed is comfortable, and the terrace will leave you wanting for nothing. We would stay here again any time.
