Lydia was incredibly welcoming and helpful in her communication. We had a huge problem with the train and came late at night, and she made a late check-in possible with her brother. That was really live saving with 2 little kids! Also the location is really great and central, you have the Bastille metro at a 2 min walk and many cafés. The apartment is small and has what one needs for a short stay in Paris, we stayed 2 nights. Lydia was very helpful recommending restaurants, too!
