We had an amazing time at Seiji's apartment.
The layout of the room was very well thought out, and we didn't lack anything.
Seiji was very helpful and was always quick to respond to our inquiries.
The location was also super convenient with easy access to the subway, restaurants, and convenience stores.
It was also in walking distance to Shinjuku Gyoen which also was really nice.
It being so centrally located did make for a bit of noise from the road, but it didn't really bother us.
All in all, it was a great place to stay, and we would definitely consider staying here again.
