Our family enjoyed our stay of 8 nights @ Room 305.
The apartment was very clean. The 2 sofas in the living area provided a good place to relax after a day out. The kitchen allowed us to prepare simple meals. We also find the drying function in the bathroom useful. There was ample space in the wardrobe for all our clothes. It was spacious and came with many hangers.
Location wise, it was a short 7-minute walk to Hatagaya station, convenience stores and supermarkets (e.g. Life Supermart and 7-11). We also enjoyed good and reasonably priced food at eateries near the station.
We will definitely stay here again for future visits to Tokyo.
