Whenever I'm in Arborea, I always stay here. Excellent hotel, clean, elegant, and with very friendly staff. The rooms are spacious and clean. The breakfast is abundant with various options, including for those with celiac disease and intolerances. The hotel has an outdoor pool and a gym.
Although Arborea might not be on many people's itineraries when they come to Sardinia, it is a charming town, with a lively atmosphere, some good food, and very friendly people. And if you do stay there, I highly recommend Hotel Le Torri. For the price I paid, the room I had was very spacious, with a balcony, ample closet space, and a spotless bathroom. The staff was incredibly helpful for my whole stay, helping me manage my time in the area and making sure that my laundry was ready for me in less than 24 hours when I returned to the hotel after a day around Oristano. And when I forgot my phone at the hotel after check-out, they e-mailed me immediately to let me know and set up a way for me to get it back before I left the area for good. Very much enjoyed my stay!
