Stayed at Heaven two times last month.
Pros;
Reasonable price (first time around 1600, next time 1400)
Good location, 3-4 mins walk to Nana Plaza, also very close to the sky train
Free fast Wifi
Clean enough
Cons,
No pool
fairly small rooms (sure there are bigger suites to the rooms I stayed at)
I would stay there again, and have no problem recommending it.
