Aida has been keeping her guesthouse for over 30 years and knows what she's talking about.
I arrived late one afternoon, and despite having a large tour group in already, they bent over backwards to fit me in.
Casa Aida is an ideal base for acclimatisation walks nearby, such as Imbaburra and Cubiliche, and their local know-how can be invaluable.
If your Spanish is up to it, talk to Aida and her daughters. They're very friendly and eager to chat. Aida also knows English, Italian, French, and a few words of Czech and Japanese. Ask her about her grandmother's engagement ring!
