There is not much to say, except that our stay at Frank's apartment was quite perfect. Everything was even better than expected. The apartment has a very comfortable size (especially for Parisian conditions) and was extremly clean. It is located in a very nice neighborhood with lots of groceries, restaurants and bakeries just around the corner. It is also very well connected to public transport as the metro (line 9), bus (line 72 which takes you to all the most important sights) and trains (line RER C) are within walking distance aswell. If you plan to stay multiple days the available dishwasher and washing machine will make your stay more pleasant. One tiny footnote would be that there is some minor traffic noise also during the night, but that surely is to be expected in the middle of Paris and didn't bother us at all. I cannot recommend a stay in this apartment enough.
