We stayed in Apartment 1 which is a cosy apartment perfectly located for exploring Dubrovnik old-town (just a 10 minute walk away, with a bakery, supermarket and several restaurants). The apartment is a nice size for a couple, spotlessly clean, and the kitchenette is well equipped. There are four apartments in the building and at times we could hear the shower/muffled voices from the next apartment, but not loudly or disruptive enough to be problem. The wifi was also a little slow and intermittent but again not any real issue.
Our hosts couldn't have been any more welcoming and gave us some great local restaurant tips. They even carried our suitcases up the flight of steps from the taxi to the property, booked a taxi for our departure and stored our suitcases between check-out and our flight on our final day.
