This is a nice modern apartment but unless you like spending 2-3 hours a day travelling back and forth between your apartment and the train station I can't recommend this place.
From most common tourist destinations such a Shibuya or Shinjuku you are looking at a one hour train ride just to get to the station closest to this place. Once you arrive you are then looking at another 10-15 minute walk back to your apartment. Do you really want to do this twice a day for everyday of your holiday?
Also there are very limited food options around the apartment and even around the station. There are no grocery stores or restaurants and the only option are convenience stores.
The train network around this area is also confusing as it's not really on any major train lines, so you'll spend a lot of time transferring and back tracking just to get home. And this is not coming from someone new to Tokyo. I lived there for seven years so I'm pretty familiar with getting around and even I found this area confusing.
The apartment is not bad but the location is really a huge let down.
