I had a great experience at Mariana's studio in Princeville! The neighborhood was very safe and nice. We could walk to Queen's bath and the St. Regis hotel. Driving to Hanalei and Princeville were very convenient. I didn't cross paths with Mariana and Carlos too much while we were there, but the few times we did they were very friendly and accommodating. The best part about the studio was all of the amenities that Mariana provides: snorkel gear, cooler, rain umbrellas, beach umbrellas. This saved us some time and money in not having to worry about purchasing these things or bringing them on the flight. The price was also very reasonable, we saved a ton of money in comparison to the neighboring hotels. The only downfall was the somewhat uncomfortable futon bed, but this was expected with the low price and the photos she provided. The unit is small, but the high ceilings and the large bathroom help to not feel so claustrophobic. Overall if you want to save some money, stay in a great neighborhood, and plan to spend most of your time outdoors, I highly recommend Mariana's studio!
