Thanks to the Host, it was indeed a lovely, comfy and safe stay in Milan, the one of the most busiest place in the world. Perfect location not only to go around the town, but also to go outside of the city since the central station is just a few block away.
I spent a relaxing time not to do anything sitting in the balcony while I was back in the flat. What I really enjoyed the most was looking at the summer sky that changes moment by moment.
