We arrived in Cannes in late September after getting the shuttle bus from Nice Airport (Tip 1 catch the local bus as it will be a fraction of the cost prob 5e each rather than the 17e each we paid), when we arrived it was bucketing down with rain and the bus dropped us in the middle of a street rather than at the train station as we expected, to find the hotel walk to the front and walk along until you get to the Marriot and turn left and walk for another 2-3mins.
Here are the hotel +/-
+
Service - We turned up drenched and although our room wasn't ready the staff said to dry up and have lunch before and then our rooms were ready, our bags were taken up and it turned around a bad start caused by the weather. On another occassion we ordered some champagne and the barman topped us up for no extra charge, great service from nearly everyone which I can't say about most places.
Price - We paid in the region of £170 in an offer price including breakfast for 2nights, for 4 star that isn't bad.
Food - The continental breakfast was fresh and the lunch we had was a revelation for ~15e, drinks were fairly priced as well compared to the strip.
Room - Odd layout but very spacious with small balcony, fridge, flat screen tv, loads of space for clothing. The fridge means you can buy water etc and keep it cool without paying the high hotel prices.
Facilities - Small gym and roof terrace with decent views and a little pool with sun loungers, think you can book a space on the beach through reception if you so wish.
Quiet - Unlike the main strip being a few streets back means it is really quiet.
-
Air con - doesn't work, meaning in September we were a little warm at night, in the height of summer would be unbearable.
Shower - Almost impossible to use without drenching the bathroom!

Some notes on Cannes unrelated to the hotel:
- There is a Barclays opposite but it doesn't have an ATM which I found staggering!!
- You will be pestered regularly by street sellers
- Service in the restaurants is very mixed, there was a small fish restaurant on the tight cobbled streets I'd recommend and Coque Le'Bruin or such was really good as well.

Bad service and ignorant: would never recommend this hotel. The so called suite is a double room wih sloppy extra beds. The service is really bad and the manager is never around to talk to you. Bathroom was not well cleaned and gross.

We don't understand the negative reviews because so far the hotel is excellent. We got a big flatscreen in the room, great personal proactive service, the jacuzzi and sundeck are really nice and the fitness room is small but good (even an spinning bike). The location is awesome just a step away from the beach, shopping street and restaurant/bar areas. The valet parking is also a nice bonus. Worthwile going. Room gets cleaned twice a day also fresh towel service, beach service.

5 min walking distance from beach and 15 min from harbour; clean, silence, good breakfast, but expensive.
