In the surrounding area there are a few bars, some of which have a limited selection of groceries to buy. There's also the levada do moinho around 20 minutes away by foot from the house which I recommend going to.
The furniture in the living room is not the most up to date and a bit creaky but other than that the inside of the house is in a very good state and quite comfortable.
Communication with Luisa has been great and she has been very accommodating regarding my questions and requests.
I should mention that it is highly advisable to have a car or motorcycle to live here since the way from Ponta do Sol village to the house is very steep. Watch out for the crossing of Caminho do Pico do Melro and ER 222, it is hard to see or hear cars coming there.
The flat was rated at only 9/10 only because the furnishings while very acceptable are not necessarily "luxurious" if you are seeking a resort-like accomodation. Casa Luisa did however have everything we needed for our stay and therefore an incredible value; we would not hesitate to stay again!
Luisa is the kindest and most helpful person one could hope for in a landlord. We were so sad when it came time to leave :-(
