This would be a great place for a couple days! The location is also amazing - super close to all bus lines and within walking distance of anywhere you’d want to do in Waikiki! I would definitely come back for a short stay, but not for another long stay for the reasons below:
My husband and I stayed here for a week and it was a little too small. To paint a picture: counter spaces include two very small side tables, a few inches on either side of the sink, and a couple feet of kitchen counter space (half of which is occupied with kitchen appliances). We did put out the small folding table that was provided, but with 1 suitcase and 1 duffle laid out, the walking space was already pretty cramped.
We live on a busy street in Boston, but found the studio to be quite noisy. We were able to hear the buses stop and open it’s doors with all our windows closed.
