The guest house is very clean and contemporary in style. The concept is to bring modern art to the building and guest apartments. We enjoyed the art and cleanliness. The location is convenient if you want to be in Southern Tokyo, near Shinagawa or Haneda Airport. There is an 8 to 10min walk to Omori Station, but not bad. There is a lot of food and markets available in the neighborhood. My only advisory is that our room was very small for a family of tall people. If you are over 6ft or a family, longer stays would require more space. We had to avoid bumping our heads in the tiny kitchen or the low mounted air conditioner that one had to squeeze past. Families with luggage will have to be creative. Also, light sleepers may take issue with the nearby above ground train. You do hear the trains, but they don't run all night. Over all, the AOCA contact person communicated clearly, room was very clean, beds were comfortable, just note the tight space and Ota location. We did love the art and concept of sharing the art with travellers.
