Stayed here for 5 nights in February and was really pleased with my experience. Hotel is quite small -- room size and amenities will not blow you away. But where Georgette really sets itself apart is on comfort, cleanliness, and location. Bed was extremely comfortable, and shower has one of those huge ceiling-mounted showerheads. Room was always spotless.
As other reviewers have noted, the location is ideal. I didn't take the subway once, and explored the entire city on foot. Walking distance to a huge number of great bars and restaurants in Le Marais. And a stone's throw from the Pompidou, which is not to be missed.
I didn't try the breakfast, but it looked good. Hotel staff is gracious and helpful. All in all, a good experience, and also a good value for that neighborhood & location. I would return.
