We had a wonderfull 4-days-weekend in Sonias little appartment near the Gare du Nord. We can certainly recommend her appartment to anyone who is looking for a romantic stay in Paris. Even though the neighborhood is rather noisy, there is peace and quiet, even with the windows opened. Sonia had made cookies for us when we came. She speaks very good english, and we had a nice long chat about what, where and how (and things we forgot to ask, we could later read in the "manual" that Sonia has made). Everything works as it should, the bed is really good and everywhere there is nice and clean. The passage and stairs up to the 6th floor can seem a little narrow an dark, but dont worry it is worth the "climb": Don't bring too much luggage, and enjoy the fabulous view to the Eiffel Tower.
