We have just stayed at Villa King with our 9 month old daughter. The villa is in a good location, just a 15 min walk into Dubrovnik Old Town or a 2 min bus ride. The bus stop is adjacent to the property which is good if you need to rest your feet after a days exploring. The neighborhood is quiet except for faint traffic noises on occasion.
Jasna and her family live on site and were extremely helpful throughout the stay. From carrying luggage up the stairs to recommendations on places to eat or visit. She even supplied us with cake on our last night which was delicious.
We stayed in the 3 bedroom apartment. It was clean, spacious and nicely decorated with beautiful outdoor spaces to enjoy the stunning views over the sea and Dubrovnik Old Town; they provided great shade for our daughter on the hot afternoons.
We managed fine but the only points to be aware of are that the apartments are up several flights of stairs and inside our accommodation there was an open, spiral staircase with one banister. This would make the accommodation difficult for anyone with mobility difficulties.
This is a fantastic base to explore Dubrovnik from. Nothing is too much trouble from your host and they clearly work hard to look after the properties. They even washed our hire car after the torrential rain storm.
