The apartment is regular size (for Tokyo standard), very clean and well lit. The self checkin/out process is easy to follow. No elevator and narrow stairs, might not be suitable for person with disabilities or with big luggage. (Though they have a unit on the ground floor which might be convenient) Going to Tsukiji is easy, simply just cross the main street. The location to the main subway line (yamanote line) is about 20mins walk, to Ginza station is about 15mins walk. The host was responsive, kept in touch with me during my stay and making sure everything is alright.
