Our stay at Nobus place was good!
The room was as advertised- nothing fancy, compact and basic.
It's located in an older building but the room itself is bright and the air conditioning worked excellent! Mattress was aging/sagging on one side and could probably use an upgrade. Also, as mentioned previously the walls are thin. We were kept up one night by partying neighbors, but the rest of our time was quiet and relaxed.
The hotel is about a 10 minute walk to the main Waikiki Strip. Lots of great food options nearby and a 7/11 less than a two minute walk away.
Nobu was fantastic and responded very quickly with any questions I had.
Overall, an affordable option for those who don't want to pay Waikiki hotel prices but still want to be near the beach and shopping.
