We loved our stay in Rovinj. The accommodation was clean and comfortable and had everything we needed and the location was perfect for exploring the old town. Nevia was a lovely welcoming and helpful host.
One thing to bear in mind is that Rovinj old town doesn't have a beach, the accommodation is listed as 10mins from the beach but this isn't a 'beach' it is steps and rocks where you can get into the water to swim. This was the only drawback we found with staying in Rovinj, with a child and no car, decent beaches were 30mins + walk away and taxis were quite expensive.
However if your looking for a town break with great restaurants, lovely streets to explore, with beaches nearby, and boat trips and ferries to the local islands, Rovinj was beautiful and this accommodation was just perfect.
