The apartment is really nice and Gabriele is an extremly friendly and great host. Everything we needed for four nights was provided by him. There even was some juice, water, coffee and a few snacks.
Although the apartment is best suited for two people, it is still big enough for three. Its location is pretty good. You can reach lots of restaurants and a supermarket within 10 minutes of walk.
If you plan to visit Bari, I recommend to stay at Secret Garden!
