Yes but it's not close to entrance of hotel .. you have to walk up and down a lot of stairs to get to hotel
No. Not only is there no parking but as it is inside Diocletian 's palace, you cannot get a car within a quarter of a mile. This is a hotel where you have to find public parking elsewhere in Split and walk to the hotel
Not onsite but hotel does provide parking offsite, and it's included in room rate.
We travelled by motorbike and we able to pay to park the bike at one of their other properties for a fee. They were very helpful and took us to the place as it was not easy to find. I believe there is also a car park just outside of the old city.
