Ratko is a great host. He answers very fast and was available during all our stay. He was also very flexible concerning our arrival time. As we had a long route and we were stopping to rest, we didn't know the time we would arrive and he was very comprehensive.
About the apartment, it's actually part of a house that Ratko shares with his family. It has two entrances so it looks like an independent house and we had our privacy. The apartment is 10 minutes from the center by car in a residential neighborhood. It's good for people with a car because it's easy to go visit the other places like Nin, Sibenik and so on without getting too much traffic jam. If the person is on foot or wants to stay near to the Zadar central beach (Kolovare) this is not the best place. However, if you go to Zadar I really recommend you to go visit the other beaches as the city beaches are not the most beautiful.
About the apartment itself, it has a lot of space for two couples or a family. It has two rooms, two bathrooms, a living room and a kitchen. It could use some repair and be modernized to be more comfortable but it's a great value for the money. We had a nice stay in Ratko's place.
