For the nine members of my family group, Louise's pair of apartments was an affordable godsend in a great neighborhood of the city for tourists. The Marais has cheap bistros, youthful/hip bars, and easy access to the tourist destinations by train, walking or biking. The apartment comfortably sleeps 9 though the living space is tight for that many people (two of whom were small children). All in all, a fine place to stay.
Thanks for your hospitality and flexibility with check-in, Louise!
