It's a lovely little studio. Matt goes to the effort of making sure you are happy during your stay and have everything you need.
It is very close to the beach, the bus and walking distance to Ala Moana. Because it is close to the hotels, you can use the local tour buses and get picked up a couple of doors down at the Hilton. It is really very convenient.
We found the pool a little less pretty than the photos and there was some work being done on improvements while we were there but overall it makes a great base to see Waikiki and Honolulu from.
Also it was reasonably quiet at night and we felt perfectly safe as the building manager is super friendly and has a watchful eye out for everyone. On the whole I would recommend the studio and Matt is an excellent host.
