Bob's place is nicely located in Lihue. It's a short drive from the airport and a short walk to a number of bars, restaurants and food truck options. The Kauai Bus stops right outside the grounds of the apartment complex and makes getting around Lihue pretty easy if you don't have a car. We weren't there for vacation, but the beach is short walk away and he's got beach gear to use.
The apartment is directly opposite Nawiliwili harbor which besides being the point were cruise ships dock is also the entry point for all cargo arriving in Kauai - so there is a lot of truck activity related to getting all those cargo containers serviced and delivered. Bob tells you upfront that the apartment can be be noisy at times - so you should be prepared for that. It wasn't an issue at night, and the AC unit provided enough white noise that earplugs weren't necessary (for us), but it was a bit intrusive in the mornings when sitting on the balcony for coffee. In the end, not a huge deal, but you shouldn't be surprised.
The apartment is spacious and has a well equipped kitchen. Makes a great home base for exploring Kauai.
