Stayed at Unai's place with 2 friends and the space was perfect for the three of us. Anything more than 3 though would be very tight, was expecting it to be a little bigger from the pictures but once inside it didn't bother us as the view was spectacular, practically a 360 view of the mountains and you can wake up to the sunrise! Pull out couch is also a double and super comfortable so no issues with the sleeping arrangement. The place is super clean there are of course small bits which have just come with time like paint peeling on the window ledge (outside) but this is nothing that bothered us. Tony, Unai's friend was super gracious and helped us out with tips of where to go and made sure we had everything we needed. As well as a very comprehensive access guide to get to Waikiki and accessing the penthouse from Unai. Great location with a 5min walk to the beach, loved our stay and made it so memorable. Would definitely come again, even just for the view!
