Firstly, this Ryokan is far from the City Centre! You'll need to take a Bus or Private Taxi to the Ryokan. For the convenience of future travellers, the bus journey is 340 yen per pax, on line 31. You should alight at the terminus station before it looks back. For your convenience, the bus stop number to alight is 8.
After figuring out your transport, Izumiya Zenbe is merely a 2-minute walk from the bus stop. The staff was polite and friendly, largely Japanese speaking with some basic English communication. The breakfast was excellent and we will highly recommend you to try it if you are staying in a Ryokan for the first time.
Unfortunately, the outdoor onsen was closed for repair and renovations, but this was compensated by keeping the indoor onsen open for 24 hours. There is a nearby public sento around which has a semi-open air onsen for those who are craving an open air bath. However given that renovations and repair works were almost complete, this problem will probably be irrelevant to future travellers.
For those who would like a private bath, it can be booked for 3000 yen. The private bath coes with both indoor and outdoor onsen; we highly recommend this private bath.
Overall this is a place to go to if you are looking for some peace and quietness during your trip and I will highly recommend this place for all travellers heading to Matsumoto.
