The apartment was lovely, very clean and modern. It's quite easy to get to as well, 15 mins from the main train station and about a 25 min walk into the centre of Milan which was very nice. Also great restaurants and bars nearby!
We did however encounter some issues at check-in. Our flight was delayed into Milan; we were stuck on the plane for about 2.5 hours before take off. We were in frequent contact with Sonia about the delay to try and give her an updated ETA on when we'd be in Milan, we gave her plenty of notice. We received responses about our delay being very inconvenient for her and that she didn't have to wait to let us check in as we were disrespecting Airbnb's check in rules even though the delay was completely out of our control. We were charged a late check-in fee as we arrived at 6pm and had an incredibly stressful first day of our holiday thanks to this. It's put me off using Airbnb in the future sadly.
