My stay was short but super!
The help and overview of things to do in Split, where to eat, what to see that I got from Krešimir was very helpful! The room was super quiet too at night - the windows are really great to close when there are lively crowds outside. The room was very clean, bed was very comfortable, and the shower was perfect!
Krešimir was extremely accommodating and helpful especially as I arrived a bit early (due to a very heavy rainstorm), and helped me to get settled. I highly recommend staying at the Guesthouse Imperator too, due of its central location in Old Town, and the nice staff.
