Very nice hotel with great facilities. The room was nicely designed, good bathroom, and was well equipped (coffee, tea, kettle, towels, radio/speaker, minibar) for a short stay. They also have umbrellas in the lobby which you can use during the day for free if it's raining.
The pool, hammam, and sauna were great to have and it was great to be able to relax after a busy day (there's also a gym).
The location is nice and quiet, as it's mainly residential. However, you still have everything you need nearby as there are bakeries, small supermarkets, and a few bars that also serve food (I recommend Le Général Beuret that's about 50m away from the hotel!) all within walking distance.
There is a metro stop (Vaugirard) just around the corner, so it's very easy to get to other parts of Paris.
Check-in and check-out were seamless, and all of the staff were very friendly and professional.
**It should be noted that you need to pay an extra security deposit on arrival of €50/night (refunded when you check-out) as this is a room in a hotel, rather than an apartment.**
