The area around the hotel is nice the swimming pool gives a charm to the place which has been cleverly built. It feels slightly dated but i have seen way worse, so it didn't feel bad. Some pieces of furniture would though need some repair (rusted tower hanger, wood in the bathroom was quite damaged by time...).
Balcony was nice, but furniture had a disgusting smell of cold tobacco so wasn't really enjoyable...
Room was good. Again dated, difficult to find some electricity to charge the phone (in the 1990s those issues didn't exist) but after unplugging the bedside table all fine.
The breakfast wasn't good... Dry cakes, tasteless croissants, etc which is to be expected in a hotel.
I had paid extra for the dinner at the hotel and do not do it ! You might have your money worth for the quantity (as it is a buffet) but quality is not there. So pay less, go outside and get some proper food, it is italy you have plenty of choice around, don't do that to yourself !
It is outside of Cagliari but well connected to transportation and in a nice environment.
The hotel gets 4 stars despite the critics as it is also cheaper than most around. So it is definitely a good ratio price/quality if you do not eat there. If you eat there, the hotel is way overpriced for the quality !
