We really enjoyed our 3 week stay in March here. The apartment is small but clean and modern with every amenity you might need for a short or longer stay. The pictures in the website are a reasonable sample of what you will find. The bed is extremely comfortable. There is enough room to store 2 suitcases, but not much more. Plenty of wardrobe and drawer space. The kitchen is small but well equiped. Don't expect a coffee maker. Many Starbucks and other Cafes to get a good caffeine fix anyway (SkyTree Town) and a "banana" bakery just a 5 minutes away that sells the most divine custard puffs ever. Shampoo, soap, paper towels, toilet paper, etc are supplied.
Location is perfect for getting around Tokyo via the Oshiage metro station. It is a very quiet, safe, residential area. There are many local attractions and shopping within easy walking distance including the 7 storey grocery, shopping and eating complex "SkyTree Town" as well as the nearby Temple site with its adjacent extensive shopping area. All Tokyo museums and public sites were closed during our stay due to the Corona Virus, but the many Parks and Gardens are delightful to visit. The Tokyo Architectural Streetscape is jaw dropping as are their huge department stores, especially in Ginza. Most have extensive prepared food outlets in their basements. No real need to cook at home or eat in restaurants, just sample the Japanese take-outs there - costs less anyway and there is more food choice.
If we return to Tokyo, this is where we will stay.
