Had a great stay here. Booked 2 rooms (requested connected or close to each other) using AMEX Certs and points.

Given suite (346 pictures similar to Escape4) and executive sea view room (348 which are the pictures from :D! above I believe).
Given breakfast downstairs for all 4 people.
Suite ready for early check in.
Service is great and they really take care of Diamonds here.
Location is excellent right outside the old city.

Only minor things:
Couldn't get late check out and was informed like 1 hour before check out (night before they said check back next morning) so bit of scramble to freshen up an vacate the room.
Got charged for phone calls concierge made for us to confirm activities...a couple of Kuna here and there so no big deal.

We flew into DBV and took the ferry to Split when we split.
Used Uber to get around and it is a great deal compared to US Uber prices.
