First off, the good - the location was fabulous. Indeed very close to a very nice public beach and in the old heart of Menton, steps away from Saint-Michel Basilica. Owner seems nice enough, and it was easy to get into the apartment. And, the apartment was larger than expected. And things generally worked. Lots of stairs, but that was accurately described and was not a problem for us.
Having said that...this apartment is in desperate need of a deep cleaning. Walls, light switches, many corners of the apartment were dirty. Black tile grout, spots of possible mold on the ceiling of the downstairs bathroom. We felt compelled to buy come bleach cleaning wipes during our stay. Also, there is a smell coming out of the dishwasher that was extremely foul, and made my fiancee sick the first time we opened it. I'm sure it's some kind of plumbing issue.
Shutters are in need of some repair also, only one set of shutters opened, closed, and locked properly.
A deep cleaning, and maybe a fresh coat of paint would have improved my rating dramatically. Having said that, if you value location above all else, than this would be a good rental.
