We stayed for 2 nights as family of 4 at the Appartement and for us it was perfect. We walked everyday from there to the old center as we liked it to explore the city and found a lot of beautiful places, restaurants and shops. We really enjoyed our time there and our host was really helpful.
The appartement is very clean, aircondition in every room and everything you need for staying there. As it is located at a strongly frequented street, I would recommend sleeping with closed windows… than it is ok!
