We had a great stay at Lyn and Jovanny's. The Condo met our needs and expectations for a 6 night getaway. The grounds of the Makaha Valley Towers were enjoyable as well. Mostly retired people hanging around the pool during the day, so it was quiet and peaceful. The Weber Genesis grills were also nice to have.
I would recommend getting familiar with the area, perhaps by reading reviews of Makaha Valley Towers on Tripadvisor. If you've been to the islands before, you know that not everywhere is built out as a resort area, and there are actually places where people live and work (imagine that!). The drive to Makaha through Wainea is a bit run-down, and traffic can snarl up with all the lights depending on what time of day you drive through. It is going to be a drive to the little bit nicer dining in Kapolei. If you're wanting to spend most of your vacation exploring the island, you'll get frustrated with the traffic in the area. However, if you're looking to spend at least half your time at the beach, some of the best beaches in the state IMO are just down the mountain from the condo and so easy to get to.
Condo was very comfortable with a nice large bathroom. Laundry is in a shared area, but was extremely convenient (same floor). They are strict on security at the towers in terms of entry- requiring proof of insurance, etc., but the staff were all very friendly.
