Hotel Poseidonia sits on Viale Europa in Arbatax, the coastal hamlet of Tortolì on Sardinia’s east coast. Its appeal is closely tied to geography: the hotel faces La Sughereta park and is near Porto Frailis Bay, while Arbatax’s working port and the red porphyry outcrops known as Rocce Rosse give the area a character distinct from a resort built around a single beach. The official hotel site describes it as a four-star property and a base for discovering Ogliastra, the rugged region where the coast meets inland mountains.
The hotel publishes an inventory of 33 rooms, including nine Executive rooms and one suite, alongside Comfort, Single, Triple and Quadruple categories. Its room pages list air conditioning, satellite television and Wi-Fi, while the official site gives room sizes and stated capacities for each category. These details are more useful than broad promotional language: travelers can compare the actual configuration and ask the hotel to confirm bed layout, view, accessibility and cancellation terms before paying.
