You're right, it does take some effort. I did it two weeks ago. I took bus 100 from Nice bus station to Eze-Bord-de-Mer (NOT where you want to go). From there, bus 83 takes you up the cliff (I mean cliff) to Eze-le-Village (your destination). Plan on a wait for the bus unless you hit it just right. An alternative is to take the train from Nice to Eze-Bord-de-Mer, then bus 83 as above. A 3rd way, and maybe the best but I didn't know it at the time, is: bus 82 or 114 goes directly from Nice to Eze-le-Village, so I'm told (verify bus numbers at Nice bus station). A 4th way: get to Eze-Bord-de-Mer by one of above methods, go to bus stop and check when next bus 83 is, if you don't want to wait that long, near bus stop I saw a sign with phone # for local taxi service; heard a rumor up on top that someone did this and it cost €25 - €30 one way, good if you could share the ride. For athletes, there's even a trail up the cliff from the lower Eze to Eze-le-Village, called the Nietzsche Trail(!)--this is a hike with a lot of uphill. MOST IMPORTANT: Watch "To Catch a Thief" before you go, it was filmed partly in Eze, starring Princess Grace when she was just a Hollywood actress and obviously before she was killed on the Corniche highway not far from Eze.
