The "b" chain includes a number of hotels in Tokyo, and a few dotted around the country. They're business hotels, but up to date, efficient, and clean. They're well marketed, and you pay a small premium over a non-branded hotel, so they won't be the cheapest, but still good value for money.

Finding the hotel the first time was a challenge. Not only is it on a side street, but it's set back from the street. Even with a full address and GPS, the taxi took a couple of passes to find it. Print out and bring the location map on the website! Apart from that, the location is good if you're going to be travelling widely around Tokyo - it's close to 3 or 4 subway lines and a couple of JR train lines, so accessibility is excellent. Note that you're slightly closer to Ueno than Tokyo station, so for the airport, use the Keisei Ueno line not the JR Narita Express, as it's faster.

Check was efficient and easy. They were offering discounts through some loyalty card, which I didn't have, so adjusted the room rate instead. I didn't test the staff's English but a non-Japanese speaker would be welcomed just as well I suspect. They have maps and area information available.

I booked a double room for more space, but it was still, as expected, quite compact. It was in a corner so an odd shape which I liked, tho' I'm not sure what a feng shui master would have thought! It had all the standard features of a business hotel: wired internet (free and fast), kettle, fridge, good quality unit bath... nothing remarkable, all clean, all in good working order. The desk was a reasonable size for working, although the lighting could have been better. There was no view (well, there was, but it was of a wall...) but then in a budget city hotel I wasn't expecting a view. The bed was comfortable and I slept well.

There's no gym, and you're in the middle of built-up Tokyo, so your morning run will be along city streets. The only peripheral facility was a public computer in the lobby, and an espresso machine (very welcome!). There is only one elevator, so at peak times (mostly first thing in the morning) expect a bit of a wait.

Breakfast was included in the price, but to be honest wasn't great. I'd have preferred to pay JPY1,000 less, and go out for a coffee shop breakfast. There was white bread, blister-pack jams, 2-3 unappealing hot items, and so-so coffee. It wasn't bad, and I've often had worse, but just nothing to get excited about.

Check out was fine, and they provide free luggage storage lockers if you need to leave your things.

If you're on a modest budget, want somewhere clean and reliable to sleep, and will be visiting different areas of Tokyo (or need to be in Kanda!), this is ideal.
