Communication with Y K was hassle-free and very prompt. Preparation for check-in, directions, amenities' usage instruction (English) was provided for an idiot-proof stay. A good base to explore Tokyo, especially if you are keen on the attractions in Ueno Park. Otherwise, Y K's place is just a couple of minutes away from the nearest station - Inaricho (Ginza line) - to connect you to the other areas in Tokyo.
Need to be mentally prepared that the bathroom and toilet area in Japan are comparatively much smaller than expected.
Whilst there is a small kitchenette in the apartment, equipped with cutleries, Y K's place does not provide any condiments for cooking. If you plan to cook, get ready to buy oil, sauces etc. Lawson, Family Mart and Mini Shop is just 100 - 200 meters away.
With prior arrangement, we were also fortunate to be able to keep our baggages in the small room downstairs after checking out.
Overall, the family enjoyed our stay here.
