We had a wonderful stay at Paolo's Appartement in the very Centro Storico of Bologna.
Sonia gave us a very warm welcome and every information we needed, included mentioning a baggage storage that we used at the day of our departure.
The Appartement is small but very smart furnitured so that it's comfortable during a few days trip. We were there at hot temperatures and satiesfied with the A/C.
You have to climb a few stairs but it is normal in most of the older buildings in the area.
If we visit Bologna we would stay there again.
