I have to agree with all that's already being said here. The hotel is a maze and it's not even nicely decorated. The staff seems not even know the word "customer service".
However, the absolutely WORST part was that when I left - I was charged for my stay for the second time. I tried to explain them I had already paid in advance and showed the receipts and all, but since their night time guard (left around 4am) couldn't understand English properly, I had to pay for extra 504 euros. I couldn't stay to argue since I was in a hurry to the airport. Afterwards, I contacted my travel agency (IAN Services) for a refund, but after a numerous promises about reviewing the situation, they didn't even reply. So, can't recommend that travel agency either.
Taxi drivers also scam tourists in this city. It's very common that they charge whatever they want if you order a taxi from San Remo to Monaco or to Nice. You can haggle the price down, but e.g. trip from San Remo to Nice can range from 100 to 200 euros.
There is no way in earth this hotel deserves to be a four-star hotel. Maybe 2. Rooms are clearly overpriced.
