We stayed almost a week at Francine's flat. Francine was great from the moment we booked, helpful with information and advice.
The flat is situated in a pleasant area, the nearest stop to the flat is Volontaires which is a 3 minute walk away, and is on the number 12 line which is a well connected line. The flat is surrounded by restaurants, and by the metro stop there are many food shops, patisseries, and pharmacies, also a cat cafe which was very cute. The flat is out of the major touristic areas but is a 20 minute metro ride from the Eiffel Tower and door to door it took an hour and a half to get to Euro Disney. Though we didn't use them there are also various bus routes near to the flat that can take you all over the city.
The flat was the right size for the two of us, it was clean and well kept with wifi and a tv. The bathroom was spacious and there was a lot of storage space for cases and clothes. The kitchen was well equipped to cook or bake anything. There was a lift up to the flat from the bottom floor so stairs weren't a problem. We stayed during a very hot week, where it reached 42 degrees one day, and Francine brought us a fan to help deal with the heat. The flat was fairly cool despite the heat and I believe that in normal weather the flat would be even cooler.
Overall Francine was a great host, we throughly enjoyed our stay and would strongly recommend staying here to anyone looking for somewhere in Paris.
