This is a great place at a great location in Paris. Close to all the Paris attractions and to the metro stations. Celine was prompt in responding to our inquiries and needs although she was not there in person. To appreciate Celine's place, it would be best to scout the neighborhood on the first day, especially Rue Montorgueil.
A general cautionary note regarding your visit in Paris:
Be fully aware of pocket pickers at metro stations & tourist attractions. Best is not to carry any valuables with you.
