Would definitely consider staying here again. Apartment was very clean, with a kitchen / dining area and couch/futon on one side, and then a bedroom and bath in the back. Balcony faces the Cavtat waterfront and sunset. I found it to be a very good value.
Nina was super friendly and helpful. She got us settled in, and arranged a private ride to the airport for 100 kuna.
It's easy to get there from Dubrovnik on the number 10 bus (25 kuna), with a nearby stop that's just a short walk downhill to the apartment. We chose this apartment for our final night because it is close to the airport.
Speaking about the airport, one downside is that the entirety of Cavtat sits at the end of DVB's runway, so there is a steady stream of low-flying air traffic. It didn't bother me because I happen to be an airplane geek who loves watching them, but also because the planes are generally landing so the engine noise isn't as loud as take-offs. We slept with the balcony door open and were not awakened by the planes.
