Mariola's place is in a great location to easily access the beach, Diamond Crater, Hanauma Bay, etc. It's only a half block away from the International Marketplace with plenty of restaurants around. Just a heads up -- many places close before 8PM. This may be due to the pandemic, but just plan accordingly when you want to go out to eat after a day of adventuring.
The condo itself was clean and I appreciated having access to a full kitchen and a washer/dryer for laundry. There was laundry detergent generously provided, but no fabric softener. (Not a big deal, but might be worth throwing in a few fabric softener sheets in your luggage as I did.) The shower head had good water pressure too. The balcony with table/chairs has a nice view of the canal and mountains. The building was quiet as well. The pool and top deck were not open while I was there -- likely related to COVID restrictions? While my visit was for only 2 nights, it would be a great place for those interested staying in downtown Honolulu. Traveling outside of Honolulu can easily get boggled down by the typical large city traffic. I forgot my snorkeling mask when visiting Hanauma Bay and just opted to rent one from a local dive shop, otherwise, driving back to the city in the morning would have easily taken 2 hours round trip on a weekday.
Just a word of caution -- parking in the city is expensive! So having free parking is a huge perk. However, I had a standard size SUV and held my breath while parking in the razor thin assigned parking spot. Any person of a "normal size" would need to enter in through the back of their car and crawl to the front seat, otherwise, you would have hit the car door parked next to them if you wanted to enter normally. Just take that into consideration before you get a Jeep and expect to fit in the parking garage. Also, the key FOB is required to access the garage. When checking out, park your car on the ground floor visitor parking and run the key FOB back up to the self-locking condo. It's only the 1st/ground floor that you can access without the key FOB.
Overall, I'd definitely stay at Mariola's again. Thanks for the hospitality!
