Gret's place was excellent!! As other reviews have said, the pictures do not do it justice.
The location was very central and I felt perfectly safe in the neighborhood where the apartment is located. The door key was very easy to use and securely locked the apartment.
For sleeping, the street is very quiet, the bed was very comfortable (firm and large -- the size of two twins put together), the linens were soft and just the right amount of worn in, and you can make the bedroom completely dark for a good night's sleep.
As for the bathroom, it was very clean and the shower pressure was great and the water hot. During our late November stay I especially appreciated the warm towel rack in the bathroom.
Another plus about this place is it is located on the ground floor -- no need to lug luggage up several stairs and on a very quiet street.
Gret was very gracious and let us check in early after our red eye flight, even cleaning the apartment herself because the cleaner doesn't work early on Sundays. She was there to let us in and give us any instructions we needed upon check in and check out was very easy. Communication was great!
I highly recommend this Airbnb and would gladly stay here again in my next trip to Paris!!!
