This place is relatively central to many districts. ~25 minutes to Tsukiji Market. ~25-35 to Shinjuku and Shibuya (depending on the line you take). Just one bus ride to Odaiba. Super close to Asakusa, Ueno, and Skytree. Definitely a great value place for its accessibility. If you're coming from Narita, it will take you about 1.5 hours to get here (Kensei Line and then Chuo-Sobu Line (local), cost ¥1039 for me). Bit of a walk from the station (~15 minutes) but it was mainly flat. There are other options that reduce the walk but it will be more expensive.
Next, the place was clean and has everything you need to stay for a good amount of time in Tokyo. There's a washing machine, detergent, and drying hangers. You dry your clothing outside on the balcony. The AC is comfortable and relatively quiet. The beds are comfortable for long stay. There's a couch w/ a few cushions + TV with a few channels. If you want to cook, there's a stove w/ exhaust fan and microwave.
The washroom has a toilet w/ sink that are separated by a folding door to the shower and bathtub. So someone can shower and another can do their business 😉.
I booked the 3rd floor and the elevator is a life saver. I never used the stairs. The front entrance and the flat entrance is the same key. Don't lose it! Note: the front entrance is locked 24/7 so it is secured. There's a buzz and cam system for the flat. Great if you have friends coming over.
Overall, I would rent again when I come to Japan. I spent 7 days and it was not enough. Thank you Jian. 👍
