Here is a list of hotels recommended by IPGP. You may get a better price than what you find online by calling them directly and stating that their hotel was recommended to you by IPGP. All hotels are in the 5th arrondissement (post code 75005), as is IPGP. The Timhotel is especially close and most IPGP guests stay there. The Hotel Saint Christophe was preferred by a few guests who had tried both.
