I stayed three nights at Angelo's place, in the green room. The location is great, it's a short walk from the train station of Bologna, and it also doesn't take long to walk to the center of the city and to the touristic areas. Plus there's a grocery store right next to the building.
The room itself was super clean and stylish! The bed was comfortable, there was a tiny balcony (though it's the first floor (not ground level)) too. There had been some problems with the air conditiong because it had been leaking water every now and then, and it did happen with me too, once or twice. I'm sure that gets fixed before the next guest there.
The breakfast was a bit of a disappointment, a coffee capsules for the coffee machine and a chocolate chip bread of some sort. I mean I don't really call that a breakfast but thankfully the grocery store was close so I could buy my own. Tea would be nice option for us non-coffee-drinkers.
One negative thing I have to mention. During my last night there, I woke up at 2 am when some other guests were trying to get inside the apartment. Apparently the door had been logged from the inside and eventhough they had keys, they couldn't get in. So they were banging the door and ringing the door bell. I had to let them in and that disturbed my sleep badly. There were also some technical issues with something (electrical?) near the front door of the apartment so there were some drilling and constructing done right next to my room. That didn't bother me because they didn't start super early.
Anyway, I can recommend the place, despite these tiny hiccups. The communication with Angelo was easy and fast and the room was, like I said, super clean and nice!
