Well, we ended up changing our plans around a couple times and booking late, as usual, so most hotels were full. Our local rep booked us into a Ukrainian style boutique hotel near Arcadia beach (Uyutny hotel if memory serves) and it wasn't half bad: great omelet for breakfast, vast rooms, ultra clean and reasonably quiet.
However, I guess guetting international newspapers and 24 hours room service would have been a challenge, so I guess the Londonskaya or Mozart next time.
Thanks again for the inputs, gents..
