Ermanno is a well organised host, very responsive in communication, and welcomed us with some nice panzerotti.
Ermanno's previous experience with some guests was not a good one, so did feel we need to be more sensitive about our use of the house.
His place is very nice, and indeed suitable for a minimum of 6 people, since there are 6 beds in 4 rooms. We were a group of 9 friends and colleagues from a few countries who met to work and spend some time together, so we used the dining hall for work as well. It was quite suitable and accommodating.
The building is close to a circulated road, so sometimes it can get a it noisy, as apparently drivers in Bari really like to use the horn :)). Other than that, the location is quite well connected to the city centre/Bari Centrale via a few bus lines or ±30 miutes walk for those who prefer it.
