Tripplo’s hotel summary
Tripplo’s analysis · Updated 20 October 2026 · How we review hotels
Hotel Nautilus Excelsior is made for couples and adult travellers who want the beach on the doorstep and a small, quiet hotel to come back to. It is an adults-only house of 18 rooms on the Poetto seafront in Cagliari, with modern rooms, balconies over the bay and, in some rooms, a private hot tub. Guests speak most warmly about the staff, the cleanliness and breakfast on the rooftop terrace, and they describe the infinity pool as calm. The trade-offs follow from its size. Rooms are compact for the rate on a bed-and-breakfast basis, and dinner in the hotel offers limited choice, so many guests eat out in Cagliari instead. Parking along the seafront is tight in high season. Couples who want a personal, well-run base by the sea will be well looked after; anyone after a large resort with several restaurants should look elsewhere.
Guests score it 9.3 out of 10 — the average across the 14 hotels we list on Sardinia is 9.0.
- The hotel sits on the Poetto seafront with the beach a few steps away, and guests keep naming the location as a highlight. Sunloungers and umbrellas are provided, and the balconies look out over the bay.
- The staff are the most praised part of a stay, from reservations and reception to housekeeping and the restaurant team. Guests describe a warm welcome and a team that goes out of its way to help.
- Several guests feel the nightly rate is high for the size of the room, given that stays are on a bed-and-breakfast basis. Late check-out costs extra, and some found too little space to hang clothes.
- A few guests would have liked more choice in the evening, and some found the hotel's own and partner restaurants less convincing than the breakfast. Wifi by the pool and in the breakfast area is described as weak.
