We stayed in Villa Kate for 4 nights in the top floor balcony room. The host was very welcoming and helpful, giving us a shortcut to the main road on our first night.
From the main road, you can walk or take a bus to either side of Dubrovnik with ease, and the buses are very frequent.
The room itself was very nice, with ample storage, a good view, great bathroom facilities and effective aircon.
Overall we loved our stay here and would definitely recommend it!
