We loved our time at the Vittoria Suite in Ostuni. It was definitely the most unique property we've stayed at to date - a recently renovated & modern version of an old school classic that is traditional to the area. It is a quaint little space perfect for a couple or a single person. Although the couch can technically become a third bed, there would be little to no privacy in the limited space. The suite was in a great location - only a 5 minute walk to many of the main attractions in Ostuni's old town - but far enough from the hustle and bustle that you weren't bothered by noise. There isn't parking onsite, however it was relatively easy to find paid (but cheap) street parking nearby (about a 2 minute walk to the room). Mary, our host, was lovely and very accommodating :)
With this style of room, I could imagine that in the warmer months there would be a real lack of fresh air as there are no windows (aside from the front door which opens onto a street) however in the mild weather we didn't find it too big of an issue. Our only real downfall was the limited supply of hot water. There wasn't enough for two short, consecutive showers - so you will need to be quick or space them amount across different times of the day!
All in all we had a wonderful time. Would recommend!
