I had a great time in Josephine's apartment! It is located in walking distance to the beach, restaurants, public transportation, and the Hawai'i Convention Center (which was my major reason to book this place). I found the apartment very clean and equipped with everything necessary. The price per night is reasonable for what you get. The view from the room leads down Ala Wai Blvd and canal, with the Diamond Head Crater in the background and a glimpse of the ocean to the right.
The building itself offers a pool, a gym, a car rental, laundromats, and some food places. While I did not try out the first four, I can recommend the Maleko Coffee and Pastries as well as the admittedly shabby appearing but very delicious Burger and Sushi place. The only thing that was frustrating in the building were the elevators. While they currently undergo renovation, it took up to 10 minutes sometimes for an elevator to show up on your floor.
The host is a very kind, responsive and helpful person, which immediately helped when my key-card refused to continue working. According to the security, these key cards are prone to failure from time to time, especially when being in close contact to a cell phone.
All in all I had a great stay in Honolulu and this apartment, happily recommending it to others, especially to those that attend an event at the convention center.
