Great location and very efficient checkin. Having two levels was fine for our family of three and the toilet and shower being on different levels worked out fine. The unit has a charming stone wall which gave the house character and charm but seemed to cause a slight musty smell. We were ok with the smell but if someone was sensitive it might bother them. The dehumidifiers and fans were helpful with this. I would assume many old buildings have this same issue. We loved the location and enjoyed Rue Mouffetard and all the cafes and late night crepes. We felt safe in this area.
