I have to admit we were a little hesitant to travel to Hawaii at first due to the recent surge in COVID, but really happy that we did, and that we stayed at Christina's place. It's walking distance to the beach and there are a lot of restaurants and shops close by. The parking space is a plus, though the spaces are a bit tight (we had a mid-size car and I think anything larger might be challenging). The Waikiki Banyan is an older building and could use a refresh, but well maintained. It's on the more quiet side of Waikiki (near the zoo and Kapiolani Park).
The condo is very clean, which was really important to me. There are cleaning supplies, as well as a broom to sweep any sand that came back with us from the beach. The beds are comfortable, though a bit softer than what we're accustomed to. Although we initially thought it odd that there was a third bed in the main living area, it was actually a big plus. We were traveling with our 20 year old son, and he slept there (giving all of us "personal space"). Plus, my son is over 6 feet tall, so he appreciated not having to sleep on a sofa bed. The kitchen is well equipped -- lots of mugs, plates and bowls; pots and pans for cooking; full sized refrigerator and stove (we didn't use the oven) with microwave; small appliances (toaster oven, rice cooker); a good assortment of cooking utensils (though could have used a spatula and ladle); and a "real" coffeemaker (not a Keurig). There were lots of towels, including beach towels, and a washer/dryer (it's a bit on the small side and Christina had laundry detergent available) located across the hall. Toilet paper and tissues were provided; we bought a roll of paper towels. The air conditioning unit works well, though in the mornings and evenings we would turn it off and just open the sliding glass door (there's a screen door to keep bugs out). WiFi is good. My son had to attend classes a couple days while we were there, and he had no problems with his Zoom connection.
Christina and Rachel were very responsive to my emails - usually responded within the hour. I had informed them that two of the light bulbs in the bathroom had gone out, more as an FYI and they offered to send someone over immediately to replace it. I declined because I didn't want anyone into the condo and there was still plenty of light even with those bulbs out.
Overall, we really enjoyed our stay and would definitely consider staying here again in the future!
