Very comfortable stay at a very affordable cost. The rooms are clean and quiet, and a convenient distance from multiple train and metro lines. Akihabara, Ochanomizu, and Ueno are also a short walk away.
Food and basic hygiene needs are extremely easy to get at any time of day, as there's a convenience store open 24 hours less than 1 minute around the corner. There is also a vending machine in the lobby with bottled and canned drinks for cheap.
The host was incredibly responsive and quick to answer any questions we had.
