From the moment I walked in, the staff were really friendly and attentive. They're definitely the best thing about this hotel. The location is very close to the Acropolis for conferences, the centre for contemporary art, and the tram line, about 10-15 minutes walk from the sea. My room was small (just enough room to walk around the bed) with a desk and TV. The bed was particularly comfortable, but the bathroom was a bit smelly and had no shower curtain, meaning the floor got soaked every time I had a shower.
Pros: staff, close to Acropolis, comfy bed
Cons: not the nicest area of Nice if you won't be going to the Acropolis, small rooms, stinky bathroom.
