Gilles' apartment is a great place to stay. It's on the 5th floor, so it gets lots of light and air. There is a lift. Things are carefully thought through and laid out and I found everything I needed to make a comfortable home for the week I was there. The hot water is reliable, the shower deluxe, especially for Paris, and the wifi worked without a hitch.
This is a great neighborhood for those looking to stay in a part of the city that is not entirely centered around tourists. One of the best markets in Paris, the marché d'Aligre, is only a couple of blocks away, and the area has plenty of neighborhood cafés, bakeries and spots for les aperos. It is also very convenient to transportation, the Ledru Rollin metro station and the Gare de Lyon. On foot, in 20 minutes you can be at the bridge to Île Saint-Louis, the trendy shops of the Marais, or the Musée Carnavalet.
Gilles himself could not have been more attentive, responsive, or accommodating. He even checked via email during the week to be sure everything was as it should be. I'd be very happy to stay there again the next time I'm in Paris.
