Where do you catch a bus from to get to split? Is it far from this hotel
Are there restaurants nearby to eat at night?
Use Google Maps to find the bus station that is near the Old City Center, or Diocletian Palace. I tried to include the link, but Trip Advisor doesn't allow that. The walk to the bus station would be no more than 5 to 10 minutes from within the palace. The roads are paved, and the side walks are either cement or marble slabs. In 2015, we used the bus to travel from Split to Dubrovnik. It took about 6 to 7 hours. It was a very comfortable and scenic ride.
As for a good place to eat, my wife and I enjoy pizza and pasta and found this place to be very good and reasonably priced, PIZZERIA GALIJA Ltd. Again, use Google Maps to find it. It is usually crowded, which is a good sign, so go early. Also, ask about the Gelato place right around the corner. Mostly locals go there, which is another good sign of good gelato and reasonable prices.
