I had a very relaxing stay at Sam's place. Check-in was very easy thanks to his instructions. He also pointed me to both a bakery and a grocery store within a 5-minute walk from his place.
The room itself is as pictured. There's a small balcony where you can hang your clothes to dry if you decide to do laundry. Sam and his girlfriend were very nice and generous. They left me a place in the fridge to put my groceries and space on the bathroom shelf for my toiletries.
In terms of location, the apartment is on a quiet street but still at walking distance to most of Milan's attraction. There are several restaurants and gelatarias 15-20 minutes walk away. If you're motivated, you can also walk to the Central train station (35-40 minute walk) instead of waiting for the bus.
If I ever come back solo, I will definitely stay at Sam's place again.
