Inside the Diocletian's Palace
One thing I can say about Hotel Vestibul Palace is that I cannot fault the staff! They were excellent start to finish, and I have no hesitation recommending the hotel based on that alone!
We stayed in Villa Dobric, an annexe building 200 meters from the main building of the hotel. On arrival we thought we could find the hotel ourselves, but really had no clue where to go, as it is inside the Diocletion's Palace. So we rang the hotel and they came and found us wandering in circles, helped collect our luggage, showed us where to go, took our car and parked it, all with good grace and good humour.
Our room was clean and adequate, breakfast was a decent continental breakfast. Our room in Villa Dobric was a little noisy in the evening, as it was facing onto a square that had restaurants and music, but it didn't bother us too much, as we are good sleepers.
When we left we were taking the ferry to Hvar Island, and we asked in the main hotel what the process was for the ferry (we had pre booked tickets online), and I was stunned and impressed that the hotel staff would collect our luggage in the morning, take it to our car, and then park our car in the ferry queue, all while we relaxed and had breakfast. Then they walked us to the ferry where our car was waiting! AMAZING service and much appreciated!
