We got to Hakata and found this hotel right near the train station, almost ruling it out given the assumption that such a location would command a high price. Fortunately, this was not so, and after our horrid experiences in Nagano we decided to spend two nights at this hotel (making it the longest stay in any hotel of our trip).

Besides being just down the street from the train station, there was a Family Mart convenience store just across the street from the main entrance, the rooms were comfortable, well maintained, and amenities available. I actually still have the provided folding plastic hair-brush from this hotel in my overnight bag.

5 of us stayed in the japanese style room

it was basic no-frills but clean and very liveable. most importantly, it was extremely affordable at less than 50 sgd per pax per night and right in the heart of things. if you want to be right in the middle of the night life however, do stay at Tenjin instead

the staff can converse pretty well in english, which is another plus point for them.

We only stayed here for 1 night on-route to Mt Aso from Tokyo, and though the room was very small, the hotel was very clean and in a very convenient location near hakata JR station. It is less than 1 minute walk away and near all the glitziness of Hakata. Hakata is such a big city with so many lights! highly recommended for the budget traveller for above average accommodation.

A friend of mine and I were in a jam and needed a room with two beds from 7:00 a.m. to around noon on a Saturday morning. Most hotels would turn people away even if they had rooms, but the Green Hotel welcomed us. I'm rating them above average because of the attention given to this special need-- a room, little drama, quick check in and even faster check out.
My only problem was that the hotel may not accommodate non-Japanese reading guest very well. I wanted to call the front desk for a wake up call and for the life of me, couldn't figure out what to dial. Zero didn't work, the phone instructions were in Kanji, Hiragana, and Katakana. There was however an alarm clock in the room, and it worked. Contacting the hotel staff with questions and concerns was difficult and should there have been an emergecy, that would have been a major problem.
Aside from the above, the bed was perfect, shower was great and I love getting a fresh toothbrush at a hotel.
