Luiz is a great host. Friendly and always willing to give advice. Speaks Italian, Portuguese and English (those are the ones I tried!)
The rooms (I stayed there twice, in two different rooms) are spacious, and clean. The beds are very comfortable. You can use the kitchen, which has most of what you may need. The shared bathroom is clean. The shower is a bit uncomfortable (old fashioned, and small). The neighborhood is quiet, and has plenty of space to park (which is not at all common for Bari).
Luiz has two beautiful cats, that stay most of the time in Luiz bedroom.
