Christels studio is a really charming, well thought-through place.
Just bear in mind that it's right under the roof and might get really warm in summer. For me this was not an issue and I enjoyed sitting on the small (roof top-like) terrace in the evening sun.
Shops and public transport are close-by. The city centre is easy to reach.
Communication with Christel was always quick and helpful. It was also nice that I could leave my luggage for a few hours after check-out.
I would recommand Christel's studio.
