Paulines appartement is perfect for ,our stay in Paris. it's literally in the center, you can walk anywhere by foot and explore nice restaurants, cafes, beauty shops, etc.
the best way to get to the appartement is taking the metro to "les halles" and go to exit: pont du jour. from there is 5 min. walk :)
the appartement has everything you need, microwave, toaster, washing machine, clean and moderne bathroom and a comfortable bed. if you have a light sleep i suggest you take oropax and a eye mask with you.
and there us no lift, but its on the third floor, so not too much stairs:)
you will enjoy your perfect stay in paris. we loved it and will come back definitely:)
