We really enjoyed our stay in Manoa. The location was great - off the main tourist path but very easy to get to Waikiki or to get groceries/needs. It was also close to the Arboretum, which was a nice place to walk.
The house was clean, with some extra nice touches of amenities in the fridge waiting for us and with plenty of fans to help on the evenings when it was a bit muggy out. There were also beach towels / toys and a cooler to take when we went out for the day. It had nice space with three bedrooms and a laundry area that would be ideal for most families.
The only real negative on the place was the ceiling height. I am 6'7" and there were several beams throughout the unit that were probably 6'3" clearance. That led to many accidental head bumps for me. This won't be an issue for most guests, but it certainly was for me.
