The house of Sandra is located in Sao Bento, a town on the northern side of Angra do Heroismo in Terceira, Azores.
Downtown Angra is 5 mins by car, the airport is about 15 mins. You will need a car to get around the island, Sandra offered her help to hire one. Taxi from the airport is 15 Euro, which allowed us to cut car hire by 1 day.
The house is spacious, clean, fully furbished, has 5 separate bedrooms and 2 bathrooms. It can sleep far more than our party of 6 (3 adults and 3 grownup boys). It seemed to be a house that is normally inhabited by long-term tenants, it did not have the "occasionally-visited-vacation-home" feel to it.
The main supermarket of the island is 2 mins by car, a large France/US style supermarket with lots of local fresh food, in case you want to cook for yourself - we did.
We were warmly welcomed by Sandra and her husband on arrival, they were readily available when needed and helped us with finding restaurants, activities, walks, etc. on the island.
As we wanted (and did) explore the entire island, the location on the outskirts of Angra was ideal for our type of travel group, and if returning to Terceira as a 2 family travel group we would probably come back here.
