We stayed in the 2D Eiffel Tower apartment. It is about a 30 minute walk to the Eiffel tower and 25 minutes to Les Invalides. It was two steps to Pasteur metro and there was a monoprix, boulangerie, greengrocer and butcher at the end of the street. The apartment is not large but is nicely furnished and could comfortably sleep 6 (there are 3 showers which would come in handy for such a group). However, the galley kitchen is small and might not really suit those who would like to cook evening meals most nights; it was missing some standard cooking equipment (tongs, vegetable peeler, salad bowl, roasting dishes) although coffee pods were kindly supplied. But then again Paris is filled with restaurants and there are several nearby. Mathieu was super responsive to all queries and was a great host.
