We fully recommend Caterina's place for your stay in San Vito Lo Capo.
The location is really great, very close to the beach (4-minute walk) and in the middle of downtown where the shops and restaurants are. There's even a really good café next door. A well-stocked supermarket is also within walking distance, so we did not use our rental car at all during our stay in San Vito.
The building has been clearly recently renovated. It stands out from the neighboring buildings, with its white walls and light-blue window frames. The apartment itself is on a 1st floor, so you have to go up some stairs to get there. When we stayed there (Sept 2020), the ground floor was still empty, but it's separated from the apartment. There are no other apartments in the building, so it is really quiet; we slept like babies after spending the whole day under the sun.
Inside, everything in the apartment seems very new. The kitchen is really well equipped, so we could do any and all cooking that we wanted.
Having the top terrace (aka solarium) is really a highlight! We usually had breakfast and apperitif there, in the the fresh air, overlooking the town, listening to the birds sing and to the bells of the monastery ring.
We will definitely try to stay in Caterina's appartment the next time we visit San Vito, and we recommend that you do, too :)
