Time of year
In the Navigli area. There are a few curious places, an house that you enter where you can find art works and bric a brac. Nearby is an historic place where washerwomen used to the laundry on the stone slabs by the stream.
I usually bring my friends to see this part of the Naviglio where women go to wash their clothes in the past...you can still see the stones where each woaen position themselves
Cute little side street with a small canal near the Naviglio Grande. It's not exceptional but a curiosity, as you can still see the stones where the laundry was done in the old times. All the area is worth the visit and worth a nice stroll around.
The canals are a lovely stroll and this small cul-de-sac has a small stream running to it's side and some vintage style houses. There was a bit of building work going on at the bottom of the turning and overall it wasn't that impressive.
When you are in Navigli or Ticinese (what I highly recommend), try to find Vicolo dei Lavandai. It's nice hidden place - old laundry place.
