Stay at Ichimaru's apartment for 6 days and it was a pleasant experience. Apartment is about 5 mins walking distance from shinjuku sanchome station entrance. I was late check in that day but I still manage to find the apartment even though it's night time ( thanks Ichimaru for the location map).
Ichimaru was a friendly host where she constant follow up with me and make sure I get in the apartment safely, and we felt so warm to receive the welcome gift! Ichimaru is very responsive to message as well, therefore if you need any assistance definitely can reach her very quickly. Such a caring host where coffee brewer is there and even hair brush is there too! Overall this is a pleasant experience staying in Ichimaru's apartment.
