When I arrived at Yini's home I was instantly welcomed with a warm smile, a hot cop of tea (since I was a bit sick) and a 30-minutes' explanation of what I can do in and around Trinidad.
My planned 2-day stay became a 5-day stay due to the amazing atmosphere, and the homely feeling.
Yini's breakfasts and dinners are excellent in quality and quantity, and aside from being a great value for your money, they were the best meals I've eaten in Cuba, aside from in luxury restaurants (which cost much more).
The rooms are clean and cozy, and the only minor nuisance is the (private) shower, which reliably provides hot water, but at a low pressure (which is a standard in Cuba's casas, sadly).
All the tours and activities you can find in travel agencies are also offered by one of Yini's friends - a taxi driver and a tour guide who speaks English well - and for considerably lower prices.
Yini doesn't speak English, but if you happen to stay during the weekend, you'll meet her English-speaking younger son, Ariel, who can act as a traslator, and regardless, a very interesting person to converse with, especially considering his age.
If you're in Cuba, you must visit Trinidad.
And if you come to Trinidad, you owe it to yourself to stay at Yini's casa.
