I spent two days in Milan for business and my experience was delightful. Valentina is a great host, she made me feel like at home, showing me the flat and a self-made guide to explore Milan and the Isola borough with very useful and nice tips. The flat is awesome, located in a typical milanese "casa di ringhiera". So, if you wanna experience a trip like a local, this place is perfect for your purpose.
The borough Isola is one of the best in Milan, full of trendy bars and restaurants in the nearbies. The perfect borough to end your day with a good meal or a relaxing drink after a day full of work or a long hike in the city.
