Ichimaru san was super friendly and responsive!!
The place has an excellent location, it has everything you may need on a daily basis (towels, shampoo, conditioner, soap, cups, utensils, iron, etc...) and a quick 10 min walk to JR Shinjuku station. We were 3 ladies and found the walk easy and the space was perfect for us. The portable wifi worked great with and never had any issues with it. Oh and the projector was a really nice touch.The mattresses on the beds were very comfortable. We went in winter and used the heat and it worked great - instructions for use were very clear. The bathroom is definitely on the small side as indicated by the pictures. We were all less than 5' 4" and found it difficult to maneuver in there. Not sure if I'd recommend this location for the elderly as indicated this is on the 3rd floor and no elevator...and the stairs are a bit steep and can be tricky with luggage.
Nonetheless, I would recommend this room to a group of 3-4 people looking for an excellent location in Shinjuku! It was close enough to all the sights and entertainment but just far enough away to be in quiet area. The kitchen didn’t have a stove for cooking but the microwave came in handy for heating food from the 7/11 and family mart less than 2 min away from the home. The balcony, while small, was a nice addition and made the space seem larger.
