BEWARE - Don't believe the hype on the web-site for this hotel - it just doesn't live up to it at all.
We booked to stay at this hotel as a bit of a last minute thing, but having looked at the web-site it seemed to offer quite a lot in terms of facilities.
Upon arrival (quite late due to a flight delay!) we were informed that our booking had been transfered to the adjacent hotel block, which has its own name and reception but in reality appears to have been taken over by the Setar. This adjacent building had the feeling of somewhere that had been pulled out of mothballs to fit in some extra guests - there were unlit areas in the main lobby, with dust sheets over the sofa's etc.
Our room was small, with furnishings that looked like they had come out of the 1970's, but it at least was clean, and remained that way with a good daily maid service.
Breakfast the next morning was very limited, and the doors to the room were closed promptly at 9:30, although this seemed to relax to 10am later in the week.
The hotel boasts floodlit tennis courts and 5-a-side football pitches, but all of these are in a terrible state of dis-repair, most are totally unusable, and the gates to them are padlocked. It must have been a wonderful place once upon a time, but not any more - it is crying out for some serious renovation.
Dining at the hotel - not very inspiring choices on the main hotel buffet, but the Kontiki Pizzaria on site (not owned by the hotel) is good, if a little limited in terms of choice, and be prepared for some pretty slow service - they get very busy and don't seem to have enough staff, although they are friendly enough and try hard.
Outside of the hotel there is little in the way of alternative dining options - there is another smaller hotel just down the road and a small complex with another pizzaria and a gelateria, both of which were good, but again if you are travelling in August, book your table early - they get full up pretty quickly with locals.
The place was dominated by Italian tourists, along with a large party of teenagers from Italy who were on a holiday camp at the hotel - this meant some pretty loud music from the stage adjacent to the pool area, which was probably the only bit of the hotel which lived up to the billing - an excellent pool for swimming in, but families beware - it is 5ft at the shallow end and 10ft at the deep end, and everyone has to wear a swimming cap - no cap - no pool !!
Sardinia itself is a nice place, but the whole area surrounding the Setar looks and feels very poor and run down compared to some of the other places we found when exploring with our hire car, and the beaches do live up to the billing of being able to rival the Carribean in places, you just have to get out there and find them.
Don't be put off visiting Sardinia, just look for a better place to stay.
