First, this place is really great and an incredible bargain. It is located on the edge of the old castle grounds, only minutes walking to Karatsu Castle. The views of the river from the room and of the castle during breakfast are fabulous. The comfortable futons and quiet comforters were great. Our twin room had a small attached bathtub and toilet but we used the wonderful private ofuro each evening. We stayed in room 201, next to the wide staircase, above the ofuro bath. This room is the most protected from the sounds of road traffic but the din of road noise is still there some. I am a light sleeper and my wife and I slept great here! If you like Japanese style breakfasts then you will love it here. We walked through the nice pine forest down to the beach, as well as thoroughly exploring the castle. We had a great lunch at DonDonTei, down the street from Riverside. The value of where this inn is located and the quality of your stay are first class, in our book. After a month in Japan, this 2 night stay was truly one of our highlights!

Absolutely nothing!

The hotel only has a very few guest rooms and every room had got wonderful river view. It's close to the Castle which you view from the outside the hotel. The breakfast was good with plenty of small traditional Japanese dishes. The staff were very friendly and helpful. Even though the suitcases were very heavy, they helped us to take to the second floor one by one.

The washroom inside the room is too small and it's better to take bath at the public washroom. The hotel is beside a busy road. It takes time for you to park your car at the opposite side of the hotel.

They provide free parking just across the road, and rental bicycles (for a fee)! Old school inn with tranquil vibes overlooking the river. Dated building and bathroom, and it felt like you went back in time! But it might not be for everyone... You can reserve the family bath for a private ofuro (hot big bathtub) session. Staffs are able to converse in English and communicated well with international travellers. Friendly and helpful staffs. I really love the kotatsu they provided in the room. And they also provide welcome drinks (after 10pm). Very near Karatsu Castle! Good spot for Yuri on Ice fans! There is a memorabilia section for the anime!

Bathroom is dated. A little hard to find if you don't know what you're looking for... They've renovated the entrance a little, so the picture on Booking.com doesn't really match. A little dusty. Old school futon, just like what you would expect to see in rural village grandma's house. You need to set up your own futon. A little further away from the shopping streets, in a quiet town. So you might be walking around in the dark trying to get back to the hotel.

Overlooking the river was beautiful. Close to the castle. Noisy road but it didn't bother us on the river side. Pleasant dining area where you could use the microwave and eat.

A long walk from the train station, 30 to 40 minutes with luggage. Steep stairs to room on second floor. Deep bathtub would make it difficult for some people to climb into for a shower. Bathroom was very small but it was better than we expected.

Beautiful Japanese style spacious room with big windows facing the river. Despite a busy road nearby, the rooms very very quiet (I slept with my window open). Excellent coffee in the morning served in Bodum glasses- a nice touch! Very friendly staff. I liked it so much I wanted to stay there again on my way back to Fukuoka, but then I had to change my plans.

Nothing.

The view from our room was amazing, as we could see Karatsu Castle and we were right on the river. The staff were very helpful and recommended a nice Japanese restaurant for dinner. We could park our car right across from the hotel, which was very convenient.

We enjoyed the very spacious room, the view of the water and the very attentive service from the staff.

The bathroom in the room was exceptionally small but we did appreciate the offer of the traditional bath option downstairs.

Very nice japanese style room. Tasteful and rich breakfast that you can eat with the view of the river. Staff was was very friendly, even though not all of them speks good English we were able to communicate. You have a free parking space on the other side of the sreeet. Highly recommaded!

- Good view

- Unclear location for parking space (Actually, this is located in opposite side of the hotel)

Lovely view over the river, close to the castle and the beach. The room was spacious.

It is on a road that has quite a lot of traffic. Having said that, none of the rooms face the road and our room was quiet.
