Andrea was a truly excellent host. He gave us loads of help in Milan, we really loved the city and his flat. He communicated quickly and well, was flexible about meeting us and keen to help and gave us a lot of tips were really around transport and sites and amenities, which were really good for finding places to eat, etc.
There are only two things that I would mention: the first is around stairs. It's worth noting that the flat is up two flights of stairs-we were travelling with a baby and buggy, so this was a bit of a challenge. The second thing is the mattress. The flat was really excellent, but it was a very hard and not terribly comfortable mattress, which meant we didn't sleep super well. Everything else in the flat was super, so it was just that one thing that wasn't great.
