As a long-time Big Island resident, I've stayed in countless Kailua hotels and condos over the years. Erika's seems to fit the trend, with a few noteworthy pros that I will certainly keep in mind when recommending accommodations for my friends and considering places to stay for myself in the future.
The price is standard for the area. A lot of Ali'i drive hotels are cheaper, but then you're not getting some of the great things that the condo has to offer - a washer and dryer, full kitchen, separate bedroom, spacious living room, etc. Erika's place is refreshingly modern and stylish - a nice break from the typical rattan and tropical motif so many condos and hotels exhaust.
The distance to the main attractions of Ali'i drive is competitive - I found that you can go down the driveway, cross the road, go down some stairs into a parking lot, go down a small side street, and come out right amidst the action in 5 minutes or so. This isn't much different than any other place nearby, and Erika's offers much more in terms of cleanliness and amenities.
The only thing I didn't like was being asked to take out my own trash and wash all dishes - when paying a $75.00 cleaning fee, I'd expect that to be included. Regardless, I would happily stay here again, and will recommend it to friends.
