We stayed at Nishu's place on Ile St. Louis for six nights recently, and had a great visit (sunny, unusually warm weather for Paris in October certainly contributed!). It is indeed a cozy, inviting two-level apartment. The bed was particularly comfy. Great place if the charm of Ile St. Louis is your kind of Paris neighborhood. Up to the beginning of our stay the communication with Nishu was excellent, and she even checked in with us through email halfway through the stay to be sure everything was all right. She had a fellow named Marc check us in and out, he was quite friendly and informative and was right on time as we were arriving and leaving. Definitely a fine place to stay in Paris.
