Super central. Modern, clean and stylish appartment. We arrived after midnight, Mario was very flexible and didn't charge extra for the late arrival. He was very friendly and super responsive. Only 2 small points; the shower leaks a lot of water on the floor. Mario says he will fix it, if not yet fixed, ask for extra towels to dry the floor. And the building (neighbours in the hallway and through the walls) are a bit noisy. So if you are a very light sleeper maybe bring some ear plugs.
Me and my friends had a great time and would definitely come back to this place.
