My husband and I spent a blissful two weeks in Sam's apartment. The location was perfect, only steps away from the supermarket and train station, and just a few minutes' walk to a lovely beach with a magnificent view of the chalky cliffs. The apartment itself was really comfortable, well-equipped, and immaculately clean. The kitchen was well stocked with everything a cook might need to prepare meals from the produce and fish available at the local outdoor market, just a block or so from the apartment.
Beaulieu is centrally located, and a local bus runs from Nice to Menton, stopping at all the seaside towns in between. Since public transportation is so easy, it really isn't necessary to rent a car at all, except to venture to more out-of-the-way towns in the mountains. Included in the rental is a secure parking spot in an underground garage, if you do choose to rent a car.
Thanks, Sam for a great vacation--we hope to return!
