We had a great residence at Antoine's AirBnB. It's very central (2 minutes from central station) and very close to a lot of shops and restaurants. The stuff at the reception were very kindly and helpful. The stairs up are very small and steep (nothing for sick and elderly people). For us it wasn't a problem, but maybe for other people, it is.
I would definitely recommend Antoine's AirBnB, because it was clean, friendly stuff and central situated. Thank you very much for hosting us.
