We had a wonderful stay at Katia's apartment. The central location in Paris is unbeatable- east Metro access to anywhere you might want to visit. Rue Montorgueil is a lively and fun area with many cafés, restaurants, bakeries, shops, and bars. We loved staying right off this street.
The unit is small but that is true of all central Paris apartments! Worked perfectly for us.
Thank you Katia and Sebastien!
