Just returned from this hotel. Let's start with the not so good points. The hotel could do with a lick of paint outside. The pool table needs replacing. The breakfast was good if a little basic. There is an issue with pigeons getting into the restaurant brought on mainly by guests not knowing how to shut a door, not the hotels fault. The private bay advertised was closed as it is dangerous and frankly I wouldn't have used it anyway (ugly concrete thing).
None of the above would put me off though, I would recommend the place for a well priced holiday in relative comfort.
That said, the staff were great, rooms were spacious and clean, the pool was lovely and immaculate. Views were by far the best in the area and quite spectacular.
Use Uber to travel everywhere. We really enjoyed our stay but didn't have main meals there so cannot comment. Local restaurants are excellent and reasonably priced. A family of 4 will get a good meal with drinks for 120 Euros including a tip. Port Saint-Jean is lovely with an excellent Steak restaurant, Ice cream parlour and shops, Art galleries and some stunning boats.
The hotel is right on the waters edge in the cove of Beaulieau, Beach is a 2 minute walk, 5mins into the village. 4 of us got the 603 bus into Monaco for Under 6 euros each way from the beach. Uber is about 25 Euros, train, 5 euros each. Uber from the airport is 30 to 45 Euros door to door and drivers are great. 5 star location it would not require much effort to make the hotel 4 star
