Sugar, spice and everything nice, this place was the sweetest guest house I’ve ever seen! Leo, the grandchild of the owners, is there to greet you and take care of you - especially if you only speak English. I traveled on my own, and as a female, never felt unsafe or not well taken care of. Clean everything, a great kitchen and bathroom and AC for the hot Dubrovnik nights. Very very close to the 6 bus, and easy to get to from an Uber. 10/10 would recommend, especially as it’s away from the chaos of Old Town!
Cozy place! Older couple who are really helpful, and their grandson helps with communication! Location is superb, walking distance to beaches, supermarket, bars and restaurants.
I had a great stay at guest house Vulic. 
The Owners are a nice older couple - they don’t speak english but should you need anything specific you can talk to their daughter or grandson. Any requests were immediately considered. 
Location is good as well, bus station and a small supermarket are only 5 minutes away. 
Would stay here again and can also recommend for female solo travellers :)
