Not really solo: Need recommendations: peaceful 10-15 day staycation in India for 3 with elderly parents (budget-friendly)

Posting this on behalf of a friend who's trying to plan a slightly unconventional trip and would love some suggestions from people with firsthand experience.

He's looking for a 10–15 day staycation with his elderly parents (3 people in total). The trip has two purposes: he needs a mental reset from burnout and a quiet place where he can work remotely for a few hours a day, think, and recharge, while his parents get a proper vacation without having to worry about household responsibilities. Local sightseeing isn't on cards much. Mayne 1-2 day in entire 10-15 days will do.

Here's what he's looking for:

• 3 guests: my friend + his elderly parents.
• A peaceful place where he can sit with a laptop, enjoy a balcony/view (mountains preferred, but beaches are welcome too), brainstorm, and work remotely if needed.
• His parents should be able to truly relax. So co-living spaces, homestays, or Airbnbs where guests are expected to cook, clean, or manage household chores are not suitable. Ideally, meals and housekeeping should be taken care of.
• Looking for places that are relatively less crowded, with reliable Wi-Fi/mobile network, and minimal power cuts or weather-related disruptions.
• Should be reasonably connected—Ola/Uber or self-drive rentals would be ideal. Swiggy/Zomato availability is a bonus, not a necessity. Basically, not somewhere that's extremely remote.
• Since his parents have some mobility limitations, a lift or ground-floor accommodation is important.
• Budget is the biggest constraint. Cleanliness matters more than luxury. A single room with triple occupancy is perfectly fine. Resorts and most hotels tend to stretch the budget, so value-for-money options are preferred.
• Tentative travel window: September to November (flexible if another time makes significantly more sense).

Mountains are the first preference, but if you know of a beach destination that fits these requirements better, that's equally welcome.

Would love recommendations for specific places, properties, or even lesser-known destinations that fit this kind of trip. If you've personally stayed somewhere that checks most of these boxes, please share your experience, along with price. Thanks!
