We stayed in a different 2 bedroom unit than the one shown in these photos that included a large balcony with a table, chairs, and view of Tokyo Tower. The units were clean, well maintained and quiet. We loved being so close to all the options in Azabu Juban and having easy access (3 min walk) to the Tokyo American Club as this gave the kids a place to swim/hang out at the end of the day and gave all of us a place to go eat breakfast when we were up at 6am during the first few days of our trip and nothing else was open. Club is members only but has reciprocal agreements with many US clubs so check before you go.
I was a bit nervous booking this place as it didn't have many reviews, however the management company was very responsive to all my requests and even scheduled a private viewing for my friend who lives in the area so she could take a look at the apartment before I booked it. The building also has an English speaking concierge on site who helped us with taxi's and restaurant reservations. I had also reserved a Western Garden Suite with 4 beds at the Prince Park Tokyo Tower but cancelled it and went with this apartment instead. After going to the area near the tower and seeing that hotel I am so glad I changed plans. The area around the Prince Park is really more for business travellers and the hotel was dated and the suites were on the ground floor near a busy road. This apartment was also about $150 a night less than the hotel. (We were travelling at a peak time in Tokyo so lodging in general was very expensive, even more expensive than NYC)
If you're a frequent user/member of the Tokyo American Club (TAC) then this place is perfect for you. It's close to the Club, which is in a fantastic area that has both culture and peace and quite.
In addition, it was very convenient with a few subway station close by, and a large shopping district only minutes away.
You wouldn't think you are actually in the heart of the city, really is a perfect place to stay.
The maids and the lady at the front desk was incredibly friendly and I felt right at home. Will stay here again on future trips.
