Yes, he should think about moving to a quieter area and/or into a suburban place, probably gated community.
People here on DR1 seem to be negative towards gated communities, but they are not all that bad. For one thing, they are clean, beautiful, safe, some even have a worldclass golf course.
There are plenty of places across Santo Domingo where he can buy an apartment in a complex that has a planta full and power outages will be a thing of the past for him.
If the heat is a problem for him (after a while it begins to get to you), then central air conditioning would be a good thing to have.
Or, he should move to a slightly more affluent area, since these areas get better electric service and of course, having a handy planta or inversor just fills the gaps.
He needs to be around people that he can be comfortable with and the beautiful thing about this country is that we got all types of people, literally. All he has to do is search in the right places.
This country is not what it used to be, today anyone can create whatever lifestyle they want and can afford. If you want a lifestyle that is a minuature first world, it's readily available. If he wants a simpler life, that is available also. As he has probably noticed, our supermarkets are packed with items from all over the world, all types of technologies are available, all the comforts are available and anything else he could ever want is readily available. So, his lifestyle really depends on him and how much is he willing to spend.
If he spares no expense, then the sky is the limit.
