Kei's house is located in a quiet area but quite near the happening Shinjuku (about 10-15mins walk). We had 6 adults and 1 toddler which is comfortable in terms of rooming but not much space to put all our luggages in the first storey. The beds in the second storey is comfortable and nice! Toilet and bathroom can be alittle small for the taller men. Overall, we had a good experience staying here!
