I stayed a week at Joseph's place and I had a great time. The room is spacious and well-equipped and the bed is also very comfortable. The entire apartment, incl. bathroom and toilet, was clean and in a good condition.
Joseph as a host was very welcoming and shared excellent suggestions (restaurants, sights, places of interest, etc.). His knowledge of Paris and his care for his guest was a real added value, what makes the room an excellent home base to visit Paris. The city center is at walking distance, as is metro station Jussieu.
There is nothing negative I could mention here and I would highly recommend Joseph's place for a visit and will definitely come back! Thank you!
