I traveled to Paris for family vacation with two elderly parents. Six people total- all of us were comfortable here. It was super easy to walk to Notre Dame- turn left out of the flat, turn left at the very next road an keep going. 15-20 min walk. Near grocery stores and a lot of restaurants. Great location. The space was as advertised- super unique and cool. The stone dusts from the amazing ceiling and walls did fall (was not a surprise since this was noted in previously reviews) on bed, suitcases, etc downstairs bedroom. It's a bit humid downstairs so there is a dehumidifier there to help (just change out the tub whenever you can). I would say if someone is not comfortable with stairs (stone and irregular surface) they should stay at the upstairs bathroom. It was VERY nice that one bathroom was on the ground floor so my parents didn't have to go up and down the stairs. If anyone staying downstairs is over 5'3'' it's hard to stand up straight in the toilet room, FYI. Not a huge deal- the shower is separate and there is ample room to stand up there. Oh, and also there is no microwave in the kitchen. But we were able to cook things on the stove top just fine. Joanna was a wonderful host, so friendly and accommodating! She arranged transportation from the train station to the flat and then from the flat to the airport on our departure. Awesome service- saved us a lot of headache and worked perfectly. Strongly recommended if you have several people with luggage especially if they are elderly. I would definitely recommend this place to friends who have no problems with stairs and want to stay at a unique space! Thank you for a wonderful stay!
