We had a lovely stay in Annalisas' apartment in April. It's a lovely clean apartment with an extensive kitchen and a smart bathroom. The balcony is great for breakfast with the sun directly on it, though if your looking for afternoon sun by the afternoon it's on the other side of the building.
Annalisa does mention the sloping roof in the apartment. I'm 6'1" tall and I did bump my head a few times but you get used to it. The bedrooms are a different matter and it's largely a crawl into bed situation as the eve's are very low, be careful if you go to the bathroom in the middle of the night. Overall it didn't spoil our stay of 4 days but a longer stay it may be more of an issue.
The situation of the apartment is good though it's a 20-25 minute walk into the centre, which is not a bad thing as you need to burn off all the amazing food that is Bologna. There are bars and convenience stores, bakery, grocers within 5 mins walk from the apt. Annalisa also has bikes available that we chose not to use but is a good option if you want to reduce the walking.
Our stay was lovely and I'd recommend the apartment, the bedrooms ideal for kids and the sofa bed in the main room for adults maybe. Annalisa was very helpful too.
