Isla Paradiso is the world included in the Island Paradise expansion pack for The Sims 3. What lots give the Beautiful Vista moodlet in that town, and what are the values? The only location I know of is 1 Alto Road, which gives a +30 moodlet.
In my experience, you can achieve "Beautiful Vista" just by having a "Beautifully Decorated" home with landscaping.
I have had "Beautiful Vista" at all my houses, regardless of the lot.
I think this may actually have something to do with the size of the house as well, since I have achieved "beautiful vista" before the rooms were "Beautifully Decorated".
Regardless, all my homes in Bridgeport, Sunset Valley, & my vacation homes in World Adventures, have had that moodlet.
Beautiful Vista is a place/lot attribute. Certain lots can provide the Beautiful Vista moodlet, these are usually found on some of the pre-packaged lots in the game. Bulldozing these lots will also remove the Beautiful Vista attribute and any new lots placed on that location will no longer provide the Beautiful Vista moodlet.
You can, however, modify the existing lot and place a home there. The game is a little finicky about the Beautiful Vista attribute when modifying lots, so be careful. It seems that most of these Beautiful Vista lots are found along the beach. I have found two of following to be "Beautiful Vistas":
- 15 Summer Hill Court (Sunset Valley)
- 345 Riverblossom Hills Drive (Riverview)
