Argentario is definitely an escape, it is on the West coast of the presque-isle associated with Monte Argentario, overlooking the Tyrrhenian Sea - a beautiful turquoise blue vista.
The host, Fabio, was always responsive by email, and his delightful daughter, Fabiola, arranged our arrival and any issues during the week. Very easy transition into the home. The house is sited on a steep gradient, built by the owners father, aesthetic and functional. Interestingly, the house has settled somewhat, with some angle to the floors, and my wife and son found this disorienting, but otherwise of no consequence. We visited during Italy's heat wave and found the rooms a bit stifling at night, even with the doors wide open. Sleeping on the lawn might be an option if the heat wave continues.
The house had electrical problems, but Fabio had these attended to on a day we were away, taking cooking lessons with his sister, Flavia, outside of Rome (strongly advised).
A rocky beach with kayaks is a 10 minute steep walk down, but with rewards of beautiful, comfortable water and great kayak opportunities.
An outdoor oven was useful for fish bought at the fish market in town (15 minutes away).
Overall a very beautiful location. Probably too challenging for anyone with mobility issues. Realize that you are remote, but it is a safe and comfortable retreat,
