We had a corner room which was a reasonable size for 3 people with an extra bed added in. The bathroom was clean with a typical Japanese wet room (combined shower / bath room). The breakfast was okay, with a range of options, though the coffee was not good. The hotel is located in a fairly corporate area, though there are some great restaurants not too far away. Tokyo tower is about a 30 minute walk away, but is in sight just around the corner.
Tamachi station is the nearest, about a 5 minute walk away. This will get you to many key sights across Tokyo and is a short hop to Tokyo station for catching shinkansen. Note that this station is remarkably busy between 7-9am in the morning, with marked lanes to try and keep people moving. It's a sight to behold, but if you don't like crowds, give it a miss at these times.
