Banrai Hotel was the first hotel of my planned trip to Japan that I was excited about: mostly because of its location (literally right outside one of the exits of Asakusa Station, which is one of my favorite parts of Tokyo), but also because it was new, modern, stylish, with a cool-looking restaurant on the ground floor. A little on the spendy side, but that's to be expected from a boutique hotel (whatever the hell that term means).
In reality, the Banrai Hotel lives up to just about all of my expectations. The location is simply UNBEATABLE. Our room, which was furnished with four twin bunk beds, was surprisingly large, and awesome for our family, which included two toddlers; the mattresses were "comfy enough"; there's no TV, which I found I did not miss. There was only a small shower (no ofuro), which was a little disappointing, as was the $10/day room cleaning fee (you get one free cleaning if you stay 3+ days, which we did, and was the only time we used it).
The laundry on the ground floor is *chef's kiss*: those industrial washer/dryer units do it all in a single go (60 mins), and don't require you to insert any detergent, making our mid-trip clothes cleaning effort cinch! 1,000 yen ($6) is an absolute STEAL for that level of convenience!
This is an absolutely excellent hotel, and one that I would not hesitate to book again in the future.
