I'll try and keep this short and sweet. I am from England and my wife is from Portland, Oregon and this was the first time we have ever used Airbnb.
First of all, this was a last minute trip, I messaged Joanna the night before we arrived in Kona and Joanna was unbelievably helpful, very prompt at replying, easy to work with and a great communicator.
The condo was amazing, wayyyyy better than it looks on the photos, if it was a hotel it would be 5* no doubts!!! Very spacious, superbly decorated, clean and full of beach gear for you to use so you don't have to buy your own so that will save you a few pennies. The condo is probably in the best location on the island, bars / restaurants / shops are 1 minute away and there is a pool & sea view from the balcony.
We were there for just 4 nights, went to a few amazing beaches, the volcano, the black and green sand beaches, snorkelled with massive sea turtles and also did a night snorkel with manta rays. Those are a few things that are a must when you are on the island.
Seriously i couldn't recommend the condo, the host and the location any more, you should definitely book Joanna's place.
