I stayed for five weeks in Teresas apartment and it was an amazing time. The apartment has the absolute perfect size for one to two people and is well-equipped with appliances for a long-term stay. The apartment is on the outskirts of the old town, which is great in two ways: You can easily walk to the city centre, but it is also quite and a really local place.
Teresa as a host was amazing as she replied very fast when I had questions coming up and helped me out a lot (e.g. I needed to print my train tickets. Deutsche Bahn.. don't ask me why you are still required to print tickets in 2022...).
I really can't recommend this apartment enough as it was great in so many ways and the price more than reasonable. I hope I will have the chance to go back to Lecce one day and stay there again!
