The flat is brilliantly clean and more than spacious enough for two people. We found the bed really comfy, and the kitchen well-stocked. The flat is about 2 minutes from the metro (line 3), which can get you to most attractions easily, and there are plenty of bus and tram stops nearby. We were able to get the the Duomo in 7 minutes, and to Centrale in 12- from these places you can connect easily to other lines/suburban trains. Fondazione Prada is only 15 minutes' walk away, and there are plenty of bakeries close by to get breakfast in.
This is a great flat if you want value for money and to be near attractions without the hordes of people. We had a great time, thanks!
