Diran was a perfect host! He even rearranged his own plans and got us at the train station when we told him that we were arriving later than actually planned. He was always replying really fast and helped us out with local tips. Only downside is, that it is really a bit outside of bari, the bus took as about 20-25 mins to the train station (during rush hour though), if you walk to the city center, you need almost an hour, but luckily we could take Diran's bikes. By bike you need about 15-20 mins and you can ride along the sea, which made the rides even more pleasant. There is a big supermarket close to the appartment (eataly), with really good food, but a little more expensive than a normal supermarket.
The appartment was clean and spacious and we had everything we needed. We really enjoyed our six nights at Diran's place and would definitely recommend it!
