We only stayed in Milan one night after we arrived from MXP and Carlo's apartment was perfect. Check-in/check-out was very easy and Carlo and his daughter were very easy to communicate with. I was concerned about the pull out mattress, but as other reviews mentioned, it was very comfortable and big enough to sleep my boyfriend and I with room to spare. The photos do not give justice to the gorgeous view from both the studio room and the roof, our favorite part of the short stay was enjoying a beer on the roof at night. The location is also very convenient, a five minute walk from Milano Centrale and the yellow line is right across the street from the studio and takes you to the Duomo in 10 minutes for only €1.50. The space is a bit tight if you're traveling with a lot of bags, so just keep that in mind if you have a long stay and big suitcases. Also, the a/c was a lifesaver, as it was about 88 degrees while we were in. Thanks Carlo!
