We had a great time staying in your apartment. I can't really think of anything the apartment itself was missing. The 'user guide' was extremely helpful. We took the bus route you listed to Eze, the train to Cannes and Antibes, and a boat to Monaco. The boat left from Le Port and was a great way to spend a day.
I wish it were closer to downtown and not on a hill, but that did not impact the great week we had. We learned that a taxi from Hotel Negrescu to the condo was 20 Euro and that was perfect.
