Location is decent; 10min walk from Rendaiji station and a 45min stroll to Shimoda. Hotel itself is old but rooms were decently maintained, apart from the shower which I wouldn't recommend using. The place itself is big with many winding corridors, most of which are humid and damp. Staff was friendly, and provided us with umbrellas to use when it was raining. We returned after 10pm and they seemed to be fine with that, after which we used the onsen till about 10:30.
The place is due for a renovation but for the reasonable price during high season (august), it's a satisfactory place to stay.
We booked this hotel last minute for short break for Oban week as can not able to book else where (Mistake!!).
All facilities, rooms, and equipment are pretty old (You can still see VHS player and VHS tape for 100 Yen). Onsen is very old as well and sauna is for one person only (must be very old design). If you love antique this hotel offer lot of vintage stuff.
Hotel staff told us to be back by 9:30pm as that is closing time, which is still early. While all facilities are still functioning, it look dirty and such need major renovation soon to restore.
