If you ever stay in Ostuni, I strongly recommend you to stay in Marcello's flat: it was a great experience. The street level flat felt like a luxury hotel to us and was at a cheap price for what it actually is. The decoration in it was beautiful and chosen with a lot of taste, and all the utilities were working smoothly (they were all brand new). Don't let the pictures of the kitchen fool you, as the cooker, even if portable, was actually an induction cooker. I must say the highlights in the flat were the bed, which was incredibly comfortable, and the shower. Marcello and his daughter were really helpful, as they gave us a map and showed us the important things around. Marcello even left food basics in the fridge for us and texted to check if everything was running smoothly and to recommend us some restaurants in the area. The flat is very central but away from the most touristy streets, located in a very sweet street where locals greet you as if you were neighbors. If you have good eye in avoiding tourist traps, you will find amazing restaurants, wine and cheese shops in Ostuni, not forgetting it is an amazingly beautiful town, 30 minutes away from a natural park with a beautiful beach.
All in all, we had a great experience staying in Marcello's flat, and I would strongly recommend it to anyone, as it was a great holiday.
