Vincenzo is a great host - he really goes out of his way to make your stay special.
In our case the occasion was my gf's 30th birthday, and I'd asked Vincenzo when I booked if he could help me reserve a birthday cake from a local bakery.
Not only did he order the cake same day, but he helped me organize a surprise - after picking the cake up himself, he waited for my signal to place it inside the fridge while we were out at dinner. He even left candles and birthday balloons - it really was a great surprise for my gf when we came home for dinner that night.
The space itself is tiny - very much like a hotel room. But it was immaculately clean, well-renovated (the building itself is several hundred years old, made of stone) and has a great shower. The location is also perfect. Right in the centro storico near the port, and a short walk to a few beaches too. There's some walking traffic outside during the weekend, but the apartment's immediate surroundings are all residential, so you don't have to worry about excessive noise from any nearby bars, etc.
Only potential downside could be that it's on the ground floor, and there aren't really any windows to open (beside the front doors) if you want a view outside.
In any case it's perfect for a solo traveler or couple visiting Monopoli for the weekend. Vincenzo really is a special host!
