Casa d'Artista is a brilliant holiday home in the historic centre of Lecce and I can't recommend it highly enough, you will have a great stay.
I can't add anything to previous reviews of the fantastic breakfasts that John and Angela provide other than to day you'll great a variety of little local treats.
Outdoor temperatures were nudging 38C when we stayed, but the apartment remains naturally cool and has several fans and air-con in the bedroom. The Casa is well equipped and beautifully decorated by John (the Artista...)
The location is a huge plus, the apartment is very quiet yet is only two roads away from a buzzing street of bars and restaurants (Mamma Elvira being our top tip for wine and great food from Salento) and just a couple of minutes from the main square, duomo etc. We were also touring the region in a car, so having (free!) parking was great, and being near Porta Napoli made it easy to get into and out of the city very easily.
John is a fantastic host, offering as much or as little advice on the area as you seek and if you are driving, we recommend taking up his offer to meet you at Porta Napoli when you first arrive as the charming streets are a bit of a GPS defeating maze with some tough corners even for a small hire car .
Overall highly highly recommended!
