Great stay with my husband and three year old daughter! We all loved the hotel's cleanliness, healthy breakfast, and the outdoor bath. Location was also perfect, as the Tokyo Metro Hibiya line was literally a 5 minute walk, even with a toddler. Room service was mostly excellent, although we did have to ask at times for amenities, and this is likely due to staffing. While the staff spoke English, it was often helpful for me to speak in Japanese for better communication.
We will stay again when in Roppongi!
