Angela's place is very ideal for a short visit to Bologna. It's located in the middle of historical center. We did not meet Angela in person but she arranged everything well and gave us tips and directions on whatsapp. She also arranged her friend Lorenzo to pick us up from the airport who was a really lovely person.
The apartment is small,in the basement of a luxury apartment. It is surprisingly bright due to a big skylight, you need to wear sleeping masks if you do not want to wake up at 6. It is usually cooler than the outside which is good for hot summer months.
I definitely recommend this apartment for a short visit.
