A great place to stay. It's about a 20 minute walk to the Duomo but it's very close to excellent public transport links with a mixture of trams and buses to help you get around. Its also on a main bus link from Milano Centrale, so easy if you're coming in from Malpensa.
The apartment is very spacious. A large lounge and two good sized bedrooms and a smaller room with a single bed (but an en-suite bathroom). It's spotlessly clean. Excellent showers in the two bathrooms. The kitchen has everything you might need, including a coffee machine.
Check in was very easy and Agnese sends you very clear instructions when you need them. We didn't need any extra help with information whilst we were in Milan, but Agnese seems the sort of person that would help with any questions.
So, I would recommend this apartment if you don't mind being away from the very centre of Milan. You are also paying for a very spacious apartment which is worth teh money.
