The flat has a great location, just in the old town. Around the corner from the main street yet quiet and private. For a family of three it was a bit small, though the beds were comfortable (incl the sofabed). The flat is quite basic, a tiny bathroom and with the bare minimum of kitchen appliances. The toaster must be placed on the floor do reach the only matching plug. So if you plan on making dinner yourself to save on restaurant expenses, this may not be the place for you.
We didn't bother to ask someone come over to do any maintenance while we stayed in the flat but overall the flat could do with some TLC, fixing faulty plugs, filling holes in the walls, etc.
The terrace has comfortable furniture, but the dreary (dead?) plants and lack of shade made us spend less time there than we otherwise might have. You can see the sea if you stand up, but the view is mostly other roofs.
We had a good time in Monopoli and the flat did the job, but compared to others we rented this one was the furthest from reaching its potential.
