My family (my wife, me and 2 teenage daughters) stayed at Guy and Dorine's place in July 2015. G & D were not present personally, but were, nevertheless, great hosts by remote control. Communication was excellent (even though we were somewhat tardy). The flat was immaculately cleaned, all the linen that we needed was in place, clear instructions were typed out and on the entrance table, and the building's concierge, Alexander, was extremely helpful. The flat is about a 10 minute walk from the major metro and RER terminus of Porte Maillot, and about 7 from a large bus stand, taxi stands, restaurants and supermarkets, including the wonderful Picard. Great view from the split level terraces over the rooftops of Paris, to the Eiffel Tower and the (top bit of) the Arc de Triomphe. I suspect that G and D live here for a part of the year and so the flat might not be always available. Grab it if available - very highly recommended !
