Our stay at Gregoire's flat was faultless. Located in a great area of Paris for eating, drinking and exploring the city, it was the perfect refuge for us.
Thoroughly clean, with a modern bathroom, (shower had good pressure and hot water), and plenty of amenities in the kitchen (the small device above the counter is an oven, not a microwave, as we discovered).
While the space is small, and tall folk will have to duck to get into the bedroom, the location and furnishings (including a huge selection of books) far outweigh it.
