My wife and I stayed at Islet View for 4 days, and loved it. The house is in a quiet and peaceful location - you can hear birds and ocean breeze, and no city sounds like cars. Awesome place to relax.
The house is a walking distance (15-20 minutes) to a boat that takes you to Ilheu da Vila rock lagoon, a great place to swim in warm ocean water. There is also a picnic area nearby (5-minute walk) with benches, tables, and stunning ocean view.
The hosts are very kind and hospitable, ready to help with questions about the island: what to visit and at what time (it matters for hot springs in the ocean, for example). They serve a solid breakfast, important to have before going on a hike.
House amenities, shared between guests, include refrigerator, kitchen with microwave oven, laundry. Bathrooms are also shared, but it was not a problem for us, since we had a different schedule from other guests. The hosts provide individual sets of towels, including special towels to take to Furnas hot springs (important detail, as water is colored there). Parking is abundant next to the house and in the nearby parking lot, which is almost always empty.
Overall, we loved the stay. Had we known what this place is like before, we would have stayed there for longer. Thank you Dr. Susanna for being a great host!
