The hotel is clean and well maintained. The guest rooms are small, however, that is to be expected in Tokyo at comparable hotels. The smallest room is ok for a single person, but when sharing the room or when staying for a longer period I would recommend booking a larger one. Bathroom ok with sufficient space. Guest room including bathroom was clean and well maintained.

Breakfast has a good selection, also for the Western taste. Internet available in guest room via cable only, wireless available in the lobby. Breakfast area and lobby nice and clean. Friendly staff.

The hotel is located very close to the big "roppongi crossing" intersection, next to Roppongi subway exit no. 5, therefore, providing very good access to town.

Stayed at the b-roppongi in Nov '12. Very good base from which to sight see Tokyo, located in the lively roppongi area and very close to other popular spots such as Shibuya & Shinjuku.

Pros:
-Location, as mentioned above, exit at roppongi station (exit 5 is closest but only stairs there, station is on the grey Hibiya line)
-Room: clean and of decent size.
-Staff: courteous throughout + spoke good english

Cons:
-Next to flyover, not an issue for me, but can imagine if you have a room facing main road, it could be noisy.
-Wi-fi only available in the lobby (quite common in Japan), where they do offer a LAN cable in the room. Not ideal if you have tablet.

Located very centrally for Roppongi, you liternally cannot move for dining options and nightlife. After having travelled around Japan, we found this to be very western area.

Very easy to find, underground station a few metres away so follow directions from hotel and you really cannot fail to find it. You've got a couple of underground line options at the hotel so is quite a good base if wanting to head to various areas of the city.

WiFi is available in the lobby and there's a little PC you can use.
We had a higher room category, on the corner with many windows.
Large room overall, bathroom was of a good size with good quality amenities and a hairdryer.
We had a little seating area by the TV and a desk so could spread out. But, not a lot of storage space for clothes. View to Toyko Tower and bright lights of the area. Was not too noisy as we were a few floors up. Only real disturbance was an earthquake one night!

Breakfast was adequate western/japanese fare, so you could fill up a little bit before going out.
Hotel staff helpful when we needed them to be, e.g. looking up airport train times, but we didn't ask that much of them.

At the end of the day, would recommend to you!

Our stay at the B Roppongi was nice. It is located right on the main strip of Roppongi and just steps from the subway. It was very easy to get to from the Tokyo subway station with our luggage in tow. We had a fantastic view of the Tokyo tower from our room. The room was very tiny and dated, though. There is very little room for luggage or bags, so we had to open our luggage on the bed, close it when done, and keep them standing behind the door when not in use. The bathroom was a decent size but also quite old and worn in.
