We spent two nights at Mathieau's apartment and unfortunately had mixed feelings about our stay.
The apartment is within walking distance from the historic city centre in a lively neighborhood with lots of small cafés and bars. Although Mathieu wasn't there when we arrived, the check-in was easy and communication during the stay was good.
However, the cleanliness was a major downside. We're by no means clean freaks, but there was lots of hair from previous guests in the bathroom and the kitchen wasn't exactly clean either. Unfortunately a no-go, especially considering that it's not the cheapest place around.
