Good location, nice small apartment with a semi-private lanai (shared with another suite), filled with tons of supplies to go to the beach, all seeming in good condition.
there was no wifi while we were there, and the options given - so use the pool wifi and be at the pool whenever using it was not an acceptable solution, and may prove difficult for any other international travelers. This seems to have been a temporary problem and should be fixed for future guests. The kitchenette was plentiful and stocked but lacking in specific utensils (only 1 -broken- steak knife)
Also helpful would have been a written information package - think hotel tips/welcome sheet- as the unit had a lot of very specific instructions (blinds, A/C, WIFI, parking, care of countertops....), and I had to refer to my emails very frequently to make sure things were being done properly. Which was difficult sans wifi, constantly going to and from the pool to access internet. I suggest printing off the instructions if you're given them before your travel dates.
As far as the price goes, you're paying for the location. Everything in Wailea is right around the corner, and it's beautiful - this was probably the most expensive/least value place we stayed at (out of 5 places in total), and the only place that did not include the taxes up front, again only past the point of cancelling and receiving a full refund were we given the full amount of the taxes, and most communication led by the hosts was done off Airbnb.
They always responded quickly to emails with concerns or questions.
