Chantal is very great host with kind attitude. Place is comfortable, clean, and location is good. She served a nice breakfast; and eating on balcony gives a special feeling.
You need approximately 20 minutes to get form Lambrate train station to Chantal's place. It is quite easy to get from green corner to city center. Doing it by walk, you can feel city surroundings. Near, about 3 min by walk, you can reach shop, which is open 24/7. Direct around of building corner, there is bus stop, where you can take bus 61 and get to city center at San Babin station, which is very close to Duomo.
