Luiz is a very friendly person, he gave us a lot of usefull tips, which made our trip to Bari better than expected :)
The flat is located in strategic place, you can find everything you need in the closest area (caffee/bar, shops, bakery and train station). Train station is just approximately 10 minutes away (visit Perulli on your way to station, you won’t regret it :) ). Bari Centrale is just 5 minutes by train, where Polignano/Monopoli need around 30 minutes to reach. Totally recommend this host, as flat is in great location, the rooms are big, clean, and Luiz is speaking english, so you will have no problems reaching to him with anything :)
