We stayed at Guillemette's place at the end of august and it was great! She left a packet of information for us in the apartment to answer any questions we had plus various brochures of sites to see in paris which were quite informative. The wifi was great, very fast and without any delays as well. One thing to note is that the apartment is without a fan or air condition making it quite stuffy at times, although we knew this coming in so really no complaints there. Overall it is a really great apartment with close access to the metro which is all you need in paris.
