Me and my friend spent couple of days at Richard's place and really enjoyed it. Richard is a wonderful host, his apartment is even better than we thought it will be and the location is simply amazing - right next to the Navigli canal and within a walking distance to the city center - and the walk is worth taking since it takes you through one of the most interesting parts of the city. Best on my review of of airbnb options, this is the best Milan has to offer.
