We stayed at Comfort Hotel Galaxie for nine nights (with two of those nights away while traveling to Monaco and Italy). As long as you don't expect a modern property with all the latest and greatest (I have to be honest -- the place is a bit aged), you'll love the place.
Be prepared for some quirks -- like the floor lights on a timer. Also, the actual keys (on a heavy key chain) stay at the front desk when you leave the building -- something an American traveler would find discomforting. Nevertheless, once you're past those "novelties," you realize that you are three minutes away from a seaside promenade full of restaurants, five minutes from the CAP3000 mall (overpriced as everything in Europe, but with a large supermarket -- quite helpful for an extended stay).
The staff is personable and helpful. (Example: we needed a voltage converter and asked where we could buy one -- within five minutes of fighting the language barrier, we had one on loan from the front desk.)
The highlight of each room is a massive balcony. There is a small fridge with minibar items -- but also room for your own stuff. Wi-Fi is free -- but could drop intermittently. There is a gated parking lot behind the building, which helps if you have a rental car.
So, the bottom line: take Comfort Hotel Galaxie for what it is -- and love it!
