The location is absolutely great, being a 5min walk to shops, restaurants and transport links to Harajuku, Omotesando and Aoyama.
We really appreciated how AJ kept us updated on a typhoon, and was so accommodating to our last minute change due to postponed flights.
The apartment was a bit more spacious than expected, and we had pretty much everything we needed.
The sound proofing is a bit limited so you will need to be ok with keeping noise to a minimum, and ok with hearing people above you.
Checking in and out was straightforward and even though we didn’t need it in the end, it was nice having the option of leaving luggage in lockers after checking out.
