Rena's house is absolutely stunning. You definitely need to be aware of the amount of steps you have to walk up and down all the time, but the views from the terrace are stunning. Having breakfast there every morning made it everything worth it :)
Besides, Rena organised our transfers from the ferry and to the airport at a reasonable price, and have his porter helping us carrying the luggage. And even left us a well stocked fridge with cake, toasts, butter, juice, coffee, water and even wine.
And the location just perfect. Once you are up back in the main street, is just a less than 5 minutes walk to the Castle, the bus stop or the main square.
