After an initial problem gaining entry to the apartment, everything went well thereafter.
The apartment looks exactly as in the photos. The bed is comfortable. The apartment is very clean. Wi-Fi is strong and consistent. There is a couch which is the only comfortable place to sit. The kitchen chairs are very uncomfortable. Except for making breakfast, I did not cook in the kitchen. But the refrigerator and stovetop worked fine.
I choose the apartment based on suitability for a solo traveler, reasonable price, and proximity to the Central Station. I planned to take several day trips. That worked out exactly as expected. However, the apartment is located about a 30 minute walk from the central tourist area. That is where most of the restaurants are found. A few restaurants are within a 15 minute walk, but when I ate out, it was usually a 30 minute hike.
Thanks to Enrico and Pam for their quick response to my arrival problems. They are interested in helping all their tennants to enjoy the time in Bari.
