Roberto and Brenda are superb hosts. They were the most welcoming AirBnB hosts that I have yet come across - going out of their way to provide us with advice for the area and welcoming us with limoncello on the rooftop. The apartment is perfectly located within Monopoli, being very close to the sea and with easy access via car to the autostrade for exploring further afield. Their apartment is comfortable and well laid out.
The only slight issue has nothing to do with either Roberto or Brenda, but concerns the parking on busy evenings - Friday and Saturday nights seem to be very busy indeed, so if you have already got a space, try and avoid taking the car because you may find yourself driving around for a long time before finding one on your return. That aside, it was a fantastic place to stay.
