We stayed a couple of nights at Mario's Air BnB and were super happy with it! The appartment was very clean and was equipped with everything one could need to prepare small meals and have a comfortable stay. Highlights were definetly the super easy check-in, the air-conditioning and Mario's fast replies.
The appartment is located in an area which isn't touristy, which we liked. It's a 10min walk to the next Metro, which directly connects you to the city centre and the main train station (10-15min commute). It's also in walking distance to the Navigli area which is super nice for drinks and food or just strolling around.
Thanks to Mario we had a nice and comfortable living experience in Milano!
