If you don't mind staying in a small room, then this is it for you. I like to think that my girlfriend and I both have a high tolerance for a cramped space but we have to admit, the room we had was pretty small. It was hard to maneuver. Also, the restroom's wall was pretty thin *ahem*.
The staff: 4/5 stars
They spoke great English. Super friendly.
The location: 5/5 stars
Akasaka exit 7 is directly across from the hotel. It's super convenient. Exit 6 is on the same block as the hotel but less than a minute walk. Also, there's a 24/7 petitmart right down the street. Totally beat the family mart and 7 eleven that's located next to the hotel.
Overall, I highly recommend the Hotel if you dont mind staying in a small room.
P.S: Please also note that when requesting for more than 1 towel, the staff gets a bit weird. I had a staff member who brought an extra towel to my room and was nosy enough to peek inside my room to see if I had more than 1 person staying with me. While I'm not entirely sure, I think there's extra fees for guests. This would explain the staff's strange behavior.
