Wow. What a treat! I had high expectations about this place, and they were all met. Although it is located out of the center, there is a convenient city bus that will pick you up and drop you right off by the castle. The guest house is also located very close to a large grocery store, many cafes, the sea, and an internet place.
Unique Qualities: From the moment that the owner, Sado, picked me up at the bus station in his car and proceeded to give me a tour of the city, I knew that I was in for a treat. They really took care of me here! His wife made me soup when I was sick. You can't beat that! Prices were extremely reasonable (less than $20 a night) and I had a small apartment with a kitchen. It's not luxurious by any means, and it's not in the city center, but they have an amazing orange-covered terrace, and it's incredibly peaceful. Sado can give you tips about anything to do and can even take you on tours into Montenegro. I definitely recommend staying here.
