I'll write this review with both pros and cons of my experience.

Pros:
Tropical Studios is a very ideal location when visiting Waikiki. Niko's place provided a fully equipped kitchen, fridge, AC unit etc. Supplies in the closet for snorkeling, beach towels, chairs, etc were all there as well so that's really convenient. Free parking is also a sweet bonus.

Cons:
When arriving, if the hosts are unable to meet you there, you'll have to get the key in the mailbox on floor 1, which can be challenging if you're driving and by yourself as parking in the area is really limited.

The bed is right next to the lanai. The sliding door is not sound proof and it gets extremely noisy in the city in all times of the day. Construction was also going on in the building over. Perhaps a higher floor in this building would be better than our 6th floor.

Parking lot/spot is also small so if your rental is a larger car and your parking skills isn't great, this can be a challenge. I recommend renting smaller cars for this airbnb.

The building is old and there is a pest problem. The kitchen had cockroaches. We saw many during our stay. I would not leave any food around or leave anything near the area. If you're afraid of bugs... I highly recommend discussing with Niko and owners if pest control was called in.

Overall the stay was comfortable and it's a great location and price to pass up.
