It is a nice place overall.
Pros:
1. 5 mins walk to the subway station.
2. Many convinient Stores and restaurants nearby.
3. You can see the Tokyo tower immediately when you walk out the building.
Cons:
1. No security in the lobby. Seems like everybody can go up to the apartment through stairs and elevator.
2. Only one apartment on one floor. Hard to get help from neighbor.
Notes:maybe you need to confirm with the owner if she will go back to the apartment during your stay before you book the place .
