I found the place nicely furnished, clean and convenient. The apartment is clean, a decent size bed and sufficient storage space for clothing. The view is great (to the East) from the 15th floor. The building is secured (lift in the building, access to pool area, laundry and to the apartment all via key card).
I found it very convenient, as everything I needed was more or less within walking distance (there is a 7-eleven and ABC store right next to the building), as well Cream Pot (great breakfast - a must) and Maleko, where Marc serves Kona Coffee! I was also impressed on how friendly and open the residents and people working there were. I never had a dull moment during my stay.
I can highly recommend Tongtong's place and I will book it again, if and when I return to Honolulu on my own.
