This is a lovely spot to stay and explore Bologna. It's in a perfect location to walk to all the main areas (two towers, market, restaurants etc.) within 10 - 15 minutes max. Federico was very quick to respond and was at the flat when we arrived.
It's very clean and comfortable and has everything you need to make coffee, or a meal in the kitchen. There are quite a few stairs to get to the top, but Federico is very clear that this is the case in his description, so we were not surprised and think of it as bonus exercise after eating loads of pasta and cheese!
I highly recommend and would stay again.
