My trip coincided with the Corona Virus panic. At first I thought I would be able to go, but with a week's delay. So ewe kept the booking for a week; I paid this, which I regarded as reasonable. Then it became clear that the whole trip would be impossible. Riccardo Luigi kept in touch, was completely understanding and followed the whole process through until my reimbursement arrived. I shall certainly try to stay at Riccardo Luigi's place when I go to Milan after this period is over (if I survive it, of course...!)
