The location is great! Akasaka station is a block away and Akasaka-mitsuke is a short 5+ minute walk. Hie shrine is very close. You can walk to Roppongi in 15 to 20 minutes.
Right outside the apartment is a bustling area full of restaurants and shops. Lots of food options and a conbini right across the street.
The room is mostly taken up by the beds so it is cramped. Barely room to walk past the beds to the door so two people will make it feel crowded.
