Family of 4 stayed 2 nights in August 2014. We found the TSAP to be a comfortable business class hotel with bonus amenities, including a washing machine in the room (buy detergent from the vending machine in the lobby on 13) and a refrigerator as well as a cook top. We used all and were happy with them. Our room on the 25th (top) floor was compact but clean and efficient, and for the money worth the expense. TSAP is a no-frills business type property and is well kept up with no surprises. The staff were helpful and pleasant. The bonus from our perspective is the location being accessible to Shibuya, Omotesando, Shinjuku, Harajuku, Yoyogi and the Meiji Jingu shrine area. My only reservation is that the ceiling height in the bathrooms is a little short, probably only 6'3" or possibly less which could be inconvenient for very tall travelers.
Traveler Notes: There is a very nice supermarket around the corner on Aoyama Dori towards Akasaka as well as a Lawson Station just a little further along if you need to pick up some items. There is also a McDonalds on Aoyama dori in the opposite direction towards Omotesando which is open 24 hours less than a block away.
