We are a family of 4 (with 2 young boys) and stayed at Villa KImberly between 16th and 23rd July 2014. We chose here initially due to the pool and cost of accommodation and we weren't disappointed. This villa is a matter of a 10 minute drive from the centre of quaint Rovinj and is situated in a quiet area called Rovinj Selo. This is a village with a shop, supermarket, 2 pubs and a fantastic restaurant, and is the ideal base for exploring Istria, Slovenia and Italy (if you feel the need to). You really can't get a more friendly place to stay, the owners live in the villa also, so are at hand with any queries, and they have 3 young children of their own. My 2 boys loved the pool, my wife loved the cleanliness and I loved the whole experience (especially the fact that food and drinks in Croatia are about 1/4 of the prices in the UK making the whole holiday even more affordable).
Highly recommended - 5 stars from us
