Our recent stay in Bari was quite nice. We actually traveled further away, but our home base was Guiseppe's place. We felt secure during our stay and even had access to park right in front of the building at no charge. During our return late one evening, we found that no parking was available, but we did find one across the street. Since it was Sunday, we didn't have to pay. So parking may or may not be free for you.
The place itself was quite nice and had plenty of coffee cups and beds for our group of four. It was very clean and well maintained. The AC units work well and certainly keep the rooms cool. There is no central air and instructions are to only have two AC units on at a time to avoid overburdening the circuit. Temperature-wise, we were comfortable. If you were to open the windows, you can get a nice cross breeze, but be mindful that there were no screens (unless we completely missed them, which is possible) to prevent mosquitoes from entering.
It is a very functional space and certainly sleeps at least 6 adults comfortably on the available beds. We didn't use it, but I think there is a pull-out bed under the couch, so perhaps another two adults can sleep there.
The place is in a great location in terms of walk-ability to old town or the central station. Once we parked, we really didn't need to move the vehicle while in Bari. Our host sent us various location to visit during our stay, which was appreciated. We even went to a recommended seafood restaurant - Delicious! (La Peschiera). Overall, we really enjoyed the place and our trip to Bari and the surrounding towns. I would recommend staying at Giuseppe's place if you want separate bathrooms, and have a group of at least four. Otherwise, it might be too large of a space. Thank you Giuseppe for sharing your "Happy Apartment" with us.
