We are a family of 5 - 2 adults and 3 children and stayed in Krk for a week. We were very impressed with this villa. It is very clean, the owners obviously take a lot of pride in its upkeep - the pool is checked and cleaned every day. All the bedrooms are a good size and the beds were very comfy. The outside space is great too, we didn't spend much time indoors.
The villa is located in a little village on the top of a hill. You will need a car but you would anywhere on this island. However, everything you want to get to is a short car journey away.
We recommend going to Vrbnik, Silo for lunch and a quick swim, zipwiring down the mountain (definitely our most memorable day) and do an excursion with 'Punat Boat Taxis'
