Kat's flat is a tiny gem, in the heart of Montparnasse with excellent bus and metro connections, yet beautifully quiet as it doesn't overlook the street. The three flights of stairs aren't very arduous as the treads of the steps are shallow and easy to climb (even for retireds).
The living area contains lots of the family's books and bits and pieces, a tiny table that two can eat at, other seating and the kitchen corner. The brand new double bedroom is light and pleasant, but you need the camper spirit for the alternative sleeping option, a mattress without much headroom on a platform over the living area, reached by quite a steep ladder. If you occupy that bed, there's a wardrobe for your things outside the shower. The shower works beautifully and also the little kettle and the microwave and the fridge. The oven didn't work, and the hob was temperamental so we couldn't cook. Instead we enjoyed selections of prepared food from the little supermarket across the street.
Kat has an art gallery nearby but we ran out of time to visit it.
It's a terrific location, the coming and going very easy, and a pleasure to have as home for those few days.
