Dugi Otok is lovely, quiet island and we were very happy with our choice. Bozo was very good at communicating and we had replies to all our messages promptly.
The house is in a lovely, quiet location and we worried it might be too quiet and difficult to get provisions from the shops etc but a combination of a hire car, a big supermarket shop in Zadar, a local baker delivering fresh bread daily, some small shops and restaurants all worked really well. Wifi also very good.
The only negative was the chap at Sakarun Beach who runs the bar and the car park. He was trying to charge £7/day to park on some grass and I made the point that perhaps he should spend 20 minutes emptying the overflowing bins on the beach (not emptied all week), rather than spend all day drinking in his bar if he wanted to justify the charge. The beach is walkable so that's what we did every day out of principle.
The beach itself is lovely and we sometimes had the whole beach to ourselves but it just needs someone to look after it a little better.
TIPS: hire car needed. Double check ferry times as they change May-June. There is a coffee machine and a BBQ so bring ground coffee and charcoal. Eat at the lighthouse restaurant next to the campsite. Think it's new. Really good fresh seafood and amazing location. Pizza in Veli Rat also very good. Visit the salt lake and national park for a day - amazing.
