We stayed at Alexis place in Paris for 4 nights and we had a great time. This place is cozy and in a very convenient location as it is near by the Guy Moquet Metro station, and all the sights of Paris easily accessible. There are also near by restaurants and bakeries, as well as a convenience store right across the street.
There are few cons however. The place is small and you will have to climb six flights of stairs to get to the room. Besides that, the place is nice and has everything you need.
