Honestly what a beautiful place to stay - I absolutely fell in love with Giovinazzo, and the flat was great, perfect balcony and view of the port and the bedroom was lovely and really quiet. The flat stayed lovely and cool even when it was scorching outside, and I think was better than the photos. Tips for future travellers are that it is quite tricky to park - lots of very tight parallel parking! Also on Saturdays the promenade in front of the flat is super busy, really good fun with everyone out, but I'd say you don't want to be getting your car out of the parking spaces in front on a Saturday!
Also whilst Romanazzi's restaurant is beautiful, the food really isn't so great. Instead I'd really recommend trying Allamuraja - best pasta we had during our stay!
