I am concerned that perhaps Kamiooka station area may not be as interesting.Well, the discriptions for each area is just as I've already mentioned. That said, it's most common for locals to live in residential areas like Kamiooka and hop on a train (or even a bike) for Yokohama Stn. area on the weekends or after work. That's just how people have lived in cities in Japan. To many of us, it's more comfortable that way: to part privacy and fun.
And as suggested, I'm not really sure if you'd call Yokohama stn. itself "fun." It's full of bigger things like department stores and huge hotels, and people walk fast minding their own business. Places like Noge (which is the area of your second link) may be able to provide you with more "fun" in terms of watching/joining people relax after work. And you can commute from Hinodecho stn.
Meanwhile, you may also notice from maps that the Keikyu line runs very close to JR and Municipal Subway, and especially JR is a convenient system that takes you to all kinds of directions. You may want to live in a place that is close to both railway company lines. As suggested, Noge is close to both Hinodecho (Keikyu) and Sakuragicho (JR and Subway), but also stations like Nakakido is right in front of JR Higashikanagawa, except that Noge has a lot more interesting bars than Nakakido.
You can also try and see if your employer will pay for a commuter pass from Yokohama stn. while you actually living near neighboring stations. You can tell them that it's more convenient to use Yokohama stn. for its faster trains. This is a practical and common way of commuting, but nowadays that the economy is lower employers tend to reject those kind of requests. But if you have a commuter pass from Yokohama, you can travel to the station for free even during the weekends.
Actually though, people living in Kamiooka area tend to spend their days off right there, because there's already enough fun for them in the area. Like I said, you've got the conveniences while you can still go to Gumyoji which is sort of like a terminal spot for the older-town aspects of Yokohama. If you don't drink and don't go to rakugo, Gumyoji/Kamiooka area might even be worth while than Noge. It's totally up to your preference.
This is something else to refer to;

Maybe sets of keywords like
不動産会社 横浜 (real estate agency Yokohama) or
不動産会社 京急沿線 (real estate agency along Keikyo line) would help. Let me also write a note for other posters.
横浜市の京急沿線に詳しい不動産会社を検索するためのキーワードについて、いい案があれば、どなたかトピ主さんに教えてあげてください。
By the way, I've never used Google to estimate trasportation times, but if you can type some Japanese station names, you should use these. Tell us if you have trouble reading any part of it.
