for example we stayed 3 nights in an Airbnb in the old town of split and paid 489 total. Paid a little more for the place in dubrovnik but the room was amazing. Also in the old town.
Overall seemed very affordable compared to western Europe.
Some amazing Gelato in split. I think it was called mare gellateria. I went there probably 3 times a day it was so good. I think a cone was like 2 euros.
