I've visited Giusy's place as a solo-traveller and stayed for 5 nights. You'd probably need a car to move around, but Putignano is really close and you can easily reach other key places in the area like Alberobello, Locorotondo, Castellana and most importantly the beautiful beaches south of Monopoli. For people that decide to "live" a little bit more the accomodation, there's a really nice and spacious terrace and also a covered patio. Also, the kitchen has everything that is needed for a full meal. Great wifi and A/C as well.
About Giusy: she's a caring and helpful host. The place was super clean and communication with her was good. When I arrived she spent some extra time with me to answer questions about the area, what to visit and where to go.
If you're in the area and you also want to experience a sleeping in a trullo in a relaxed environment, it's definitely a go-to accomodation!
