On the coastal road passing Koper and Izola follow the road signs to Portorož and later to Piran. When you arrive at Bernardin just turn right and go downhill till the roadblock which limits the town access.
Parking in Piran is very limited and expensive; however hotel guests can drive with their car undisturbed to the hotel on the Tartini square. You can leave the vehicle for a short moment near the hotel at the entrance to the Tartini square.
The hotel has one entrance from the Tartini square and one directly from the street before the square.
