We had a great stay in Diego's flat! We were very thankful for the air conditioning. We really appreciated having a kitchen/fridge and made use of the two separate relaxation spaces and the laundry. These were very helpful and appreciated. We also loved having a nice table and kitchen where we could relax with an espresso or glass of wine.
The location was INCREDIBLE. It was really close to absolutely everything (including a delicious trattoria just across the alley) but wasn't loud and still felt like the flat itself was tucked away. Diego was very quick to respond to any issues and provided helpful information. He even booked a taxi for us when we departed for the airport, which was very helpful due to an early departure.
The bed is modest but comfortable and I slept very well. Despite the panoramic window views, which are stunning, the shutters work well to keep it dark and peaceful, which made for good rest.
You may be able to see spiral stairs in the photo, so just be cautious of those if you have mobility issues. There is an elevator to the top of the 4th floor and you have to take the stairs to reach the main entry of the flat. From there, there is a bed on the main level (a couch type flat bed) and spiral stairs to get up to the main bedroom with closet, desk, etc.
Overall, we would stay here again! Diego was wonderful, the flat was great, and I can't imagine a better location for a stay in Bologna.
