Our party was five adults - parents and three adult (~30 yr old) children. The condo was great for this group. The master and twin bedroom are private, and, fortunatey, we have a family member who is comfortable with the lack of privacy of sleeping it the living space on a sleep sofa. The sleep sofa IS comfortable.
The lanai is incredible. Undoubtely you have read that already, but it runs the full length of the three west/ocean facing rooms - master bed, living room, and twin bedroom. It is accessible from all three rooms. Note it faces west, so you won't see Diamond Head from the lanai, but what you will see is a beautiful park next door (not another high rise!) and an active, beautiful water front. The kitchen/dining area is very well designed. There are three chairs and a bench at the table. It was spacious for 5 adults. 6 adults could get tight if you are big (we are not). We only made coffee and ate carryout, but I am pretty sure I could have cooked a great meal in the kitchen had I not been on vacation.)
The key thing to consider are the bathrooms, especially if you are booking becuase it has two baths. The showers are both great - spacious, good water pressure, hot water if you want it, and really well designed. The washlets (combination toilet/bidet - worth a try if you have no experience with a bidet) are cool. They function like a toilet if you don't care to use the bidet, but you shoudl try it!.
BUT, before booking you should be aware that the master suite is one room - bath and bedroom in one contiguous space, with no privacy including the toilet. If you are OK with that, you will be really glad you booked this condo.
