Luca's little apartment was very clean and actually much better than the photos. The bathroom and the shower were very nice, the kitchen was new, and the bed was fairly comfortable. The location is good--it is in a nice area with lots of restaurants and bars, also close (easy walk) to the metro, Navigli (area with lots of bars), and Ticinese (cute boutiques and shopping). The check out is early (10 am, which Luca states clearly on the page, but it was still inconvenient for me because my flight was late in the evening and Luca couldn't offer luggage storage for more than a couple hours). Very good value.
The only drawback was that I found the neighbors extremely noisy. It is a shame, because the apartment looks to a back courtyard and there is no traffic noise at all, so it can be a very quiet apartment at times. But both the next door neighbors and the upstairs neighbors were making an unreasonable amount of noise all four days I stayed there, starting very early in the morning. This isn't the host's fault of course, but something to think about if you plan to spend a lot of time in the apartment.
