Nir's place was great! There's plenty of cool restaurants and bars nearby but it's also less than a five min walk to get to the subway which will take you to the Duomo and other sites.
Nir's directions to get to his place from the train station were perfect and easy to follow.
I had messaged Nir the day before about what time we would be arriving. The day of, our train was delayed by an hour and we had no way to communicate with him. Not only did he wait for us but he actually met us on the street and took the time to show us maps and gave us a lot of helpful tips!
