My husband and I stayed in October from Sunday to Friday. We received a warm welcome at the metro station and they were very flexible with our check in time as we were arriving in the evening.
The apartment itself was beautiful. Yes it is small but more than sufficient for our stay and was far better than a hotel. It had a very homey and welcoming feel to it. The apartment also had charming character and included more than we expected (such as drinks, a few snacks and some oil and spices for cooking). The kitchen was well stocked for us to make meals throughout the week. The neighbourhood itself was lovely. A bakery and corner store were located just up the street and there were several restaurants on the street as well.
The location was perfect for us. We walked to several places with no issues, but the apartment was also located minutes from the metro to get around town.
Though we didn't require much, the hosts were open with communication and provided information about the area and city.
Hopefully one day we will get to return to Paris, and we would love to stay here again! I would recommend this for any person traveling either alone or with a travel partner.
