We (myself, husband, and two teens) had the pleasure of spending nearly a week in Wahiba's apartment. I will say up front that the only thing that was (briefly) not comfortable about the place was out of Wahiba's control. Our first two days there were extremely hot--about 105F/40C. Once the temperature went down just a little, everything was perfect. Fans and a sort-of air conditioner helped keep the air moving and things were very comfortable. The apartment is so thoughtfully kept up with lots of amenities (including a well-stocked kitchen) and a ton of style.
It was a short walk from several Metro stations. I recommend getting off at the Daumesnil stop and buying your baguette traditional from the Les Boulangers de Reuilly--winners of the best baguette in Paris competition last year.
But back to Wahiba--she is readily accessible and reaches out anytime she thinks of something that might make you more comfortable. We felt so well-looked after and enjoyed staying in this neighborhood. Highly recommend.
