Sonia's flat was just perfect. Although we did arrive very late just before midnight and she was not at home she did manage that somebody did bring us the key. The view at night to the "Tour Eiffel" is just outstanding and the cozy flat is located very close to the "Gare de l'est" and "Gare du Nord" and absolutely in the center of Paris. However, I can highly recommend this cute accommodation. Thank you so much Sonia. Greetings from Switzerland!
