I highly recommend staying here if you plan to explore Oahu, due primarily to its location and Gerri's hospitality.
By car, its location is minutes away from Ala Moana mall, Waikiki beaches, and the highway. It's also easy to walk to Waikiki and nearby food joints, which helps a lot after a long beach day. The condo comes with a parking spot, to facilitate your travels.
We stayed with up to 7 people at a time, to help split costs. It was tight, but we made it work: 2 each in two bedrooms, 2 in a sofa bed in the living room, and one air mattress squeezes into a bedroom. What impressed us though was Gerri's place came stocked with all the essentials to house so many people: beach towels, bath towels, extra linens, beach chairs, boogie boards and even an umbrella.
Food and drink options nearby are also solid. There's a Brew & Foam coffee shop in the building for early morning. and late nights can be spent at Waikiki Brewing, across the street.
All in all, we had a wonderful stay. Highly recommend it!
