Stayed in this hotel for 1/2 day only because close to airport and that transportation was complimentary...it was NOT. Apparently transport is offered at 6a,7a and two other times. We had to leave for our 4am flight at 1:30a and I called the front desk to arrange a taxi (this was mentioned at check in). Instead the front desk told me that a taxi was "not available." I became lived. After arguing, the front desk picked up the phone and found a taxi for us 30min later.
The room was like staying in a hostel, so basic; actually I've stayed in better hostels. The space was somewhat clean, but felt untrustworthy. Bed was a hard foam mattress, very firm. There were no toiletries. He'd to ask for bathroom towels. There is a pool and workout center that looked decent but did not use.
Hidden gem: indochinese restaurant Ginza a few block walk away was excellent.
We survived without too much hassle here, but will never return and do not recommend this place. Try The HQ hotel next door, looks newer and probably will feel comfortable staying there.
