Uomisaki Hotel

Good location near the water, shuttle bus is nice to get to and from Atami Station. Didn't test the staff's English, but some forms and bits of information were in English. Nicely insulated, didn't need heating in late January despite it being pretty frosty, but there was the standard air conditioner unit available. Good public baths on the property. I only tried the open-air bath at the 11th floor of the south building but it was plenty nice, and very pleasant in mid-Winter. Wi-fi seemed fine. Nice Japanese washlet toilet with heated seat (I think)

Like many places, no tattoos allowed in the public baths (onsens) - officially. It's unclear if that's actually enforced, though (saw one or two with tattoos bathing). The main building is pretty run-down and the south building (they are next to each other and attached) is just holding up - both are pretty clearly from deep in the Showa era. Didn't make 16,000yen feel particularly reasonable for two including dinner and breakfast on a Monday, but also not too bad. Also, dinner/breakfast buffers were alright, not great, not bad. The views aren't amazing from the south building if you're below the fifth floor or so. Didn't check from the main building. Skip using the bathroom in your room and use the public baths unless you're very shy (but then, why stay here?)
