Gianluca's place comes highly recommended.
It's located on a quiet street just inside of the old town and is easily reached if driving from Bari airport.
Having never visited Lecce before I had plenty of questions and found Gianluca and Ivana extremely helpful.
The accommodation itself is beautiful, in the style of the old city it's a cosy and clean place to stay that is minutes walk away from Gelatia Natalie, (make sure to pop there early and buy a famous pasticciotto to have with your morning coffee!)
In short we found this a fantastic place I stay within walking distance of all the sights, we would definitely book again and look forward to our next trip to Lecce.
