A very nice apartment with everything you might need for your stay, very clean and comfortable. The location is perfect - we bought subway passes that were never used, because all the attractions are within 30min walk, and there are a lot of restaurants within 5min. There is also a big supermarket and a nice cafeteria literally across the street.
Luciano's hospitality was also great - he answered all our calls and questions and even came and met us at the Porta Garibaldi station because it was raining when we arrived.
Overall, based on the listings we reviewed, it's probably the best price/value apartment within walking distance of the main Milan attractions.
