I booked this hotel because it was on a bus line (#5) between the airport and Piazza Roma (Venice island) and the hotel has an airport shuttle service (8 euro fee). Also, it advertised itself as a four star hotel and I paid a price that was commensurate with that.
I do not know how hotel star ratings are awarded, maybe there are different standards for different countries. However, in my opinion and in my experience, this place is not even close to a four star hotel. In general, there was a worn appearance, the lobby furnishings were dated and very modest and there was no in room safe. More importantly, there was a lack of cleanliness. The carpet in the forth floor hallway was filthy with large stains and the shower had dirt/mole on the caulking.
