Pros: Lahaina is a quiet, cute town that's mostly residential. There are a few shopping areas nearby and the Whaler mall is a few min drive. Island Vintage Coffee has superb coffee and breakfast, Leoda's is great for lunch and dessert, and Merriman's was excellent fine dining. On our next trip, we'll probably try Kihei for a change of pace -- it's also more centrally located to Haleaklea, Wailea beach is close, etc.
Unit is clean and modern and exactly as posted. It is cozy -- I can't imagine 4 adults staying there -- people would be stepping over each other, but for a couple such as us, it was perfect.
Door has keypad entry -- no keys to misplace.
Cons: Wifi was spotty -- pretty slow at times to where I couldn't watch a show on my iPad or page took forever to load on my phone. Not sure if that's a Hawaii thing and not necessarily the hosts' fault, just an inconvenience.
Also water in shower was consistently lukewarm at best. One morning I had to take a fully cold shower, which was not a great start to the day. :/
Overall, stay was great, though, Unit is clean, modern, and exactly as listed. Much better than a hotel and we had a blast.
