Definitely agree with the pervasive opinion that 20/50 in The Goblet is prime real estate. Beautiful waterfall right off the side, pool bar right out the front door, it's a wonderful location.

Other than that, I really like the small plot 27/57 in Shirogane. Straight shot to the housing markets, right beside a Market Board, and one of the isolated hot springs is just a short walk up some stairs. Most importantly though, there's a lovely little waterfall right behind it! Was super happy that I was able to snag one during the initial Shirogane housing rush.
