Mika's place is a whole house located near Nogata Station. When you look at maps it is in Shinjuku area but not really the central one so it's a bit far from the crowded and busy shinjuku life. The house is located near A LOT of restaurants, convenience store and local brand shops! I was travelling with a relatively elder family and they really liked the surroundings of the house, they said its very calm but have a lot of things we can look around and shop.
About the house, it is very clean and you can tell that the host maintain the place really well and there are instructions in a lot of places in the house near the amenities, so you dont have to browse through the manual book that placed in the dining table. But my only concern is that i think 1 shower room for a 3F house is not very convenient, as the group might consisted of 8 up to 12 people and takung turns for shower time in the morning or evening could be a hassle. but the toilet and sink that is available in every single room is very convenient thanks to that :) (but i find it kind of weird that in each room next to the sink there's a stove... better remove the stove and maybe replaced it with shower room ;)) and also the house have elevator access its really helpful when your group consisted of elders. Overall i would like to reccommend the place to the people who likes calm neighborhood and need to book the whole house for themself/group :) I enjoyed my stay! Thank you Mika :)
