This is a 10/10 accommodation and perfect for anyone visiting Japan. This was steps from the Tokyo metro and in a very cute area in town. It's less than 15 mins away to shinjuku and on a major line. Extremely convenient.
Yong's loft is beautiful and very cute. It can comfortably fit a couple and/or a family of 3 (double bed on bottom and 1 person on the loft on the top). It's clean and very well equipped. Yong really prepared the loft with a lot of additional amenities (hair dryer, shampoo, conditioner, iron, tissues, hangers etc). We really felt she went above and beyond what we expected. She even lended us an adaptor because we didn't have ours. Excellent value.
Yong was always easy to contact and very quick to reply. She provided a PDF that was detailed and so helpful for our trip including instructions for a couple options for each airport transportation, tips and tricks for the city, recommendations of places etc.
This was such a memorable stay for us - we wish we could have stayed longer!
