It's a little confused from the airport to the place by bus, and also time consuming. So if you don't know where to go and which bus to take, turn left right after going out of the airport and bus stop is opposite to train station. Hop on number 33, it takes almost 30mins to arrive. We came in the middle of a summer day, so searching, waiting and staying on the bus are tired and easily to lost patience, seriously.
We didn't have chance to met Mr. Marcello, but whenever we need help or guidance, he always replies through viber asap. He sends us all information, prepares breakfast. If you arrive at the same time he comes back from work, he could give you a lift at the airport (sadly we came in the morning). Mr. Marcello is a helpful host for sure.
His apartment is clean, tidy, and comfortable. The room is well-prepared. I definitely rate 5 stars for the place. The dog is friendly and quite, so don't be afraid of him, haha. I like the clean and large space from bathroom to kitchen. Nearby is a local pizza restaurant, you can try and it tastes okay. Only cash and Italian.
The only inconvenient point is time consuming to travel. We need to calculate exactly bus schedule, cause to go to Bari center will take around 40mins and bus only comes every 20mins, also takes some time to go on feet. Though when we travel back from Bari, arrival stop is few steps away only.
Overall, the place has nothing to complaint and if you don't mind to go back and forth in distance, I recomdment this place as a quite and mindful place to stay.
