This service apartment is close to JR Ooimachi station, which is only one station away from Shinagawa. Very convenience if you want to connect to Narita or Haneda airport.
The place is well designed, with everything you need for a long stay. It is new and clean with enough room to move around for two people.
It is next to the main road, close to the junction so you might hear some noise at night. It did not bother us much.
All in all a nice place to stay.
