I stayed in Enricos house for 1 night due to mis booking i did :) and i would say that Enrico is very accommodating host. He made sure i was OK and make sure all the things i need in the house is there even if its for 1 night. Location wise the house of Enrico is in a perfect location to everything. few minutes walk to piazza maggiore and all the important sight of Bologna. Definitely would come back to his place :)
