We stayed here for a week in late October/early November, and we really enjoyed it. Our apartment was simple but comfortable, with its own tiny kitchen, adequately equipped with just a two-burner stove and a microwave (no oven or dishwasher). I was glad we chose one of the slightly bigger apartments, because at this time of year you don't spend all your time outside on the patio, and I suspect the smallest apartments might have felt a bit cramped.
In front of the apartments, between them and the busy road, there is a wonderful cactus garden, which is a local tourist attraction in its own right - visitors come just to go round the garden, but residents can visit for free any time, of course. And looking beyond that, there are splendid views out to the west - I imagine the sunsets in summer could be spectacular.
The local town (Forio) is lively, a bit touristy of course, but not at all in a tacky way. You can walk there in about 20 minutes, or there are buses, which can be amazingly crowded. They don't seem to run to any sort of timetable, but they are reasonably frequent.
As others have reported, VIlla Ravino is exceptionally well run by friendly, helpful and hospitable people. For example, we arrived on a dark wet evening, without a car, and one of the family cheerfully offered to drive us down to the local supermarket and wait while we did some food shopping.
I would thoroughly recommend this place. It's simple, well-situated and very good value. In fact, I couldn't put it better than the poster who wrote 'recommended to like minded independent travellers looking for a bit of character and no frills.'
