To start speaking about the apartment in a perfect location (not too far for any place in the city) is too reductive. Jean Christophe is an amazing person (and traveller) that will not simply host you but will show you its city and its hidden places, sharing time and experiences with you.
The place is good both for couples or solo travellers as you have your own privacy, but it is strongly recommended to go there also to spend time with this amazing host!
