I stayed at a condo in Maui last year for a week and it was wonderful, so I expected the similar experience at Aston Beach Tower. After spent a week here, I found that the Aston has almost nothing comparable, not even close. If Aston is a 4-star hotel/condo, the Maui one would be a 7-star (and it was cheaper than Aston)!
This is basically an apartment building - there is a tiny tiny lobby, bedroom-size reception, no bar, no restaurant, a 500 sqft swimming pool that nobody uses, a pool table covered by dust. The room was good, kitchen was well equipped (but again, not comparable with the Maui one). The view would be great if you live above 17 floor (that passes the Aston circle in front of it) and your view isn't partially blocked by your neighbour.
The location is the only thing I feel good about it - it is a street away from waikiki beach (which is always super crowded). It is also on the KalaKaua ave, which is full of high-end shops and restaurants. So you will have plenty of things to do if you are bored about beaches.
