We LOVED our stay in Paris and this was largely because Lory's place was in a PERFECT location (in the heart of the left bank, 1 min walk to metro, 5 min walk to the Seine and Notre Dame, 10 min walk to Jardin De Luxembourg). The street (St Andre Des Arts) and place St. Michel are very lively with lots of cafes and great places to eat. With the liveliness comes a bit of noise, but it was worth it to us. The apartment itself was quite comfortable, especially the bed. It was small but had all the basics we needed. Although we never met Lory in person, she was consistently very responsive to our emails and arranged for her colleague Slo to meet us. He was fabulous (even carried both our bags up the three flights of stairs!).
We would definitely stay here again.
