We can confirm what was already said in other reviews: these people are really nice people. We arrived very late and they had been waiting for us and filled the fridge with breakfast for the next day.
We explored Rhodos with our rental car. The house is ideal for that: all places on the Island are within one hour drive. Lindos is 20 minutes driving, the airport and Rhodos-City both one hour. The closest village with supermarket, fresh backery and multiple restaurant is Genadi, this is only 2 minutes by car.
If you are looking for a sandy beach where the water is not so deep, go to glystra beach, about 10 minutes drive in the direction of Lindos. The double espresso at Capri di Pizza (10 minutes drive along the road to Lindos) is definitely worth a stop.
