We just stayed at Sakura Sky Hotel for 4 days. The complementary breakfast is very limited, but the konbinis (7eleven or the like) are everywhere (approx 100 mtr) and offer a great scala on foods at all hours. Subway station Kinshicho is very close by, and makes traveling everywhere in Tokyo easy. For a stay in Tokyo i would definitely reccommend also getting a Toei/tokyo metro subway ticket for 24, 48 or 72 hours, for unlimited travel.
The room was small, but had everything we needed and the cleaning of bedsheets, room and towels is done everyday, unless you want it otherwise.
There is 24 hours reception and also free soda/coffee, micorwave 24 hours as well as some free complementary bathroom items, lotions, hairpins, facemask etc.
Definitely a good priced hotel at a good location near the Tokyo Sky tree.
