I stayed at Cosimo's house in Nardó for a week in May and had a wonderful time. The house is thoughtfully and stylishly renovated, with wonderful roof terraces that catch the sun all day. It is located down a quiet lane in the historic centre of town, which is perfect to get a sense of the buzz, whilst being just a hundred metres or so from the main square. Free parking is available about a 3-4 minute walk away. Cosimo is very welcoming and kind, and had left a selection of local foods and wine on arrival. He and his brother are also on hand and very responsive if you have any questions. Overall, I couldn't recommend this destination highly enough.
