Harold was a perfect host - attentive, good communicator, informative. I stayed for 1 week for a conference at MiCo which is a short 10 minute walk away. The metro is only 5 minutes from the apartment and grants you access to the entire city quite readily. Parco Sempione is 10 minutes South and is really beautiful. I loved the city.
The apartment is quite large, especially by European standards, with 3 full bedrooms and 1 smaller one, all of which are comfortable, and well laid out. The pictures and description were 100% accurate. I would recommend this place, without reservation, for either business or recreational travel.
