We go to Sabaudia since 15yrs and since we now have 1.5yr old baby we decided to go to a beach which was supposed to offer all the comforts. We just rented the ombrella+long chairs, we were not guests of the hotel, hence I cannot comment on the accomodation.
The beach service is very expensive for what you get: we paid 900 eur a month just for shadow+3 long chairs; not being hotel-guests you are relegated in the far corner of the beach, over 300m away from the toilets and with several steps on the way, which is a problem with the pushchair (hotel guests have the places reserved in the front, which is more convenient).
Even worse, there is no smooth access to the beach and with the pushchair you have a long staircase to cope with (you can use the elevator only if handicapped and still you would have some steps before the beach).
Being in the far right corner means that if you need to buy something to eat/drink the bar is so far away that you are better of going to the next beach which is much closer.
In general this is a family-oriented beach but the facilities for external guests are poor; I would reccomend to go to the adjacent beach COALSA which has a smoother access for prams and costs exactly half of the price and the sea and the shadow are exactly the same!
We also chose this beach because it is one of the few with a dedicated parking area, unfortunately in the weekend, when there is a huge crowd and there is no chance to park in the street, it is reserved to the hotel guests while it is available during the week when you do not need it because there is plenty of parking space outside.
