Yacine was so great with us. It was very easy and quick to communicate with him by cell. He was very quick to respond. And he helped us when we had any question as he is willing to help the hosts.
The apartment was very good to spend a week in Paris with the family however it is much better if you plan to stay alone or together two adults. Hence, I would say it is has the average size for Paris' standards. The apartment was ready cleaned before we arrived, thus it was ready and tidy as advertised with all the details. The furniture, the kitchen and the bathroom was new. The kitchen was ready to cook if you need. The neighborhood where it is located is well communicated either with RER B/underground from Denfert-Rochereau Station. It took 10 minutes (3 stations) to St Michel /Notre-dame. So, it is very convenient.
We would highly recommend it.
