We stayed in the Villa del Quarzo for about 2 weeks in April. Francesco was a great & very friendly host. Communication via WhatsApp was very easy, he gave us great instructions around the house and also was very nice to give us restaurant and activity tips around the area.
The house is located near the sea and there are also swimming access points via the rocks in walking distance to the house - only possible to use for swimming when the sea is very calm. For a more accessible sand beach, a car is needed.
The house is nice and clean. For longer stays, like ours, that also included some remote work time, some more & and more up to date furniture & equipment would have been useful. But all in all - it was a nice experience.
