We had a wonderful time staying in Angelo's Jo House... it really is a beautiful apartment with many nice design touches throughout the apartment. Bathroom & master bedroom are particularly lovely! The apartment was faultlessly clean, Angelo was easy to deal with & everything was pleasant about our stay. It is well located - fairly central & pretty well connected to the main sights/nice parts of Milano via tram. Only issue there is that it's impossible to buy tickets for the tram from that location! (More of an oversight on ATM's part than Angelo's, though!)
The beds are comfy, the space is nice & you have everything you need there (except an oven, toaster or microwave, but realistically you don't need those in Milano!). The parking on site proved difficult for us as it is communal & therefore completely 'luck of the draw', but great if you can get a spot. Overall I'd highly recommend both Angelo & his lovely apartment :)
