Very good cost benefit aptm!
Location: great! Few minutes waking to waikiki beach and the main restaurants and stores.
Communication: very good! The host was very flexible and tried to help us with everything we needed (including late checkout since there were not other reservation the day we left)
The apartment: simple, but good space to relax, work and sleep. Spacious and the kitchen was well equipped. The balcony is great. It was also clean and organized.
Parking space: free parking space some blocks from the aptm. Which for waikiki I think is good, since many aptms don't have parking space.
Minor details: the host is very detail-oriented on the instructions, which for somethings is good, but expect to read quite a bit to understand all the rules (nothing to worry about) and how to park your car. Also the single mattress I felt is too soft and could be replaced and a blackout curtain could be missed if you don't tolerate light in the morning.
Overall I liked very much and would recommend the aptm and the hosts to everyone. Would definitely stay there again!
