We had a good stay at Vincent's appartment. We had the middle room of 3 rooms they rent, so you have your own room which you can lock when you leave, and you share the kitchen, bathroom and toilet with people from 2 other rooms. This was fine, but it might be a bit busy sharing one shower with 8 people in the morning.
We didn't meet Vincent, but we met Lindsay, who was very helpful in explaining everything.
The location was good. It is a 5-minute walk to the old town square and there is a supermarket just around the corner.
