The Jay Hotel is a relatively small hotel with around 30-35 rooms. It's ideally situated for the beautiful promenade, as well as Nice's many bars and restaurants. The hotel manager is friendly and helpful. For us, the areas where it could do better are: size of the rooms and storage space - if you ignore the kitchenette, we had one wardrobe, no drawers - not really enough for a 4 night stay; configuration of the bathroom - eg, the position of our lavatory made usage rather challenging (be advised if you are over 6 feet/180 cm tall); finally, breakfast was typically chaotic as the room just isn't big enough to accommodate the numbers (hence chairs being moved around, and even brought in from reception).
If the Jay Hotel could make a few tweaks to make it feel less cramped, it would be a great hotel.
