First, San Michele is a friendly place that, whilst small, has some lovely restaurants and bars as well as supermarkets and banks. There are two EV charging points now, if that's your thing. It's about 10k from Ostuni and about 15k from the Adriatic. This means prices are much cheaper than in Ostuni or on the coast. It's still well situated for exploring Puglia with Alberobello, Lecce and Gallipoli for example being short drives away.
Second, this place is 2mins walk from the square yet is quiet at night. It's a recently modernised traditional dwelling in studio style. There is an open plan living/cooking/eating/sleeping area with separate bathroom. The large bed is in an alcove off the main space and there's a foldout sofa for extra sleeping spaces. The kitchen has a gas hob and table top oven/grill if you want to cook something simple (though why, with all the lovely local cuisine on offer?).
There was no problem parking on the street opposite the front door when I was there.
