I found this hotel out of sheer frustration...I opened my internet browser, typed in "Cannes Budget Hotel" and Hotel Alnea popped up.
The location could not be better; it is found a mere 3 minute walk from the train station, and is only 5 minutes from The Croisette. In fact, the hotel is closer to the public and free beaches.
The young couple who own the hotel REALLY make you feel at home, as it is almost like staying in a b&b. After checking you in, they make sure you are fully comfortable, and that all your questions are answered.
I cannot speak for all rooms, but as a solo traveller, I was quite pleased with the room's size. The room was clean, didn't reek of smoke, and the soundproofed windows helped cut out the noise of cars passing at all hours of the night. There was a small tv with 20 channels, as well as a safe,hangars, stand up shower and large sink, and a comfortable bed.
So I don't go on forever, if you are looking for a cozy,warm, and centrally located hotel for a good price, stay here. If you are a solo traveler, I highly recommend you stay here. The owners give you their mobile phone number in case you have questions or emerencies,so its not like the big shot hotels who would only care if you disappeared because then who would pay for the room?
Cannes is a wonderful and safe town, have a great time.
