I stayed at Piero's apartment in May 2022 for 8 nights.
It's perfectly located in the old town, very convenient yet quiet, and has a great roof terrace. Being an older house it has a cooler temperature which is just what's needed when it's 26-30 degrees outside, also helped by the air con.
Piero and Paolo are great to deal with and are very helpful, I would recommend staying in their apartment if you're planning to visit Lecce.
