The home is about a 15-20 minute walk from JR Shinjuku Station (East exit) and a 5 min walk from the nearest metro train station. It is in a quiet residential street which is well lit at night time and very safe.
The apartment is serviced by an elevator and was very spacious for Japanese standards. My husband and I pushed the two single beds together and slept comfortably.
The bathroom had a handy feature (similar to an inbuilt split system) to dry our clothes after washing (using the washing machine in our room), however there weren't enough hangers to hang things to dry! So small washing loads will be needed.
The bathroom was also a welcomed spacious area. Toilet, basin, shower/bath were separated. Water pressure was good and water temperature could be controlled electronically.
Our hosts were prompt with their responses and instructions whilst basic was adequate. However some further instructions re: waste disposal and other tips would have been helpful.
Overall our 7 night stay was comfortable and fuss-free. We will definitely be back again!
