This condo is a great location for the excellent snorkeling at Makaiwa Bay. It's a nice walk through the Manoku fishponds to get to the "beach club." Of course the beach is open to anyone, the "beach club" just allows use of the lounge chairs - no towels or other services offered. There are some shade trees and a cafe.
The Mauna Lani resort area is designed with ample space between different developments (e.g. The Palms, The Terraces, the hotel, etc). The view from this condo lanai is of undisturbed lava flows with a glimpse of the ocean beyond - and even Maui if the air is clear enough. Very relaxing and beautiful.
This condo unit has its own locked garage, so you can safely leave all you snorkel kit, bicycles etc in the garage. The owner has left some snorkel kit, boogie boards, etc.
Casual cycling in the area is nice - but as usual for Hawaii, there is not much signage and the condo does not supply an area map. Go to the hotel reception and ask for a useful map of the resort, and then be prepared to cycle on paths that look like they might just be for golf carts - and maybe are, never figured it out. Plenty of cycling outside the resort, especially if you don't mind cycling on a bike lane adjacent to a busy highway.
The condo itself is nice in overall appearance, with comfortable beds and good linens, but the details are the problem. The carpet is stained and not stretched correctly anymore. The lanai floor and rails haven't been cleaned for some time so are grubby. The kitchen supplies are well used and offer the usual random assortment of odd things that you find in a vacation rental, but never the thing you really want to find (in this case, a sharp knife, a plastic cutting board for onions, rather than the fancy wood one that should only be used for bread. And salad spinner, see comment below about water.). It did have a nice rice maker, coffee maker, electric kettle, toaster and wine fridge. The main refrigerator was broken during our stay - another fridge was already stuffed in a spot by the dining table, which was inconvenient but acceptable for our short stay. It looked like the main fridge had been broken for some time already - you might want to ask about the appliances before booking. The stove is radiant heat, which is not easy to cook on if you are used to induction or gas.
The tap water in this area is heavily chlorinated. You might prefer to bring a Brita filter, or buy drinking water.
