We really enjoyed this downtown location- it was close in walking distance to tons of cool stuff and very short drives to some awesome snorkeling. usually it rains the entire time I'm in Hilo so I didn't think I'd need AC, but this time it was HOT. There were plenty of fans luckily but if you need AC I wouldn't roll the dice.
The area can get a little sketchy after around 8pm- lots of people wandering around the streets, as with any downtown area in any city. They asked for money/cigarettes a couple times but really they were overall harmless, I just wouldn't suggest walking alone at night.
The apartment was very nicely updated and had every amenity I could think of. The beds were super comfy and having 2 bathrooms was amazing. The tile in the shower does get slick with soap so be careful! There's only really seating for 3-4 on the couches for watching TV and we traveled with 6 - but there are extra chairs for playing games- just not comfy enough to watch a movie though.
Checking in was a little confusing since it mentioned an app, but I just used the code she texted me and that worked fine for our stay! I'd definitely stay here again.
