I stayed at Lina's for 3 weeks and I have to say that it was perfect! She is a really lovely lady, full of resources and so enthusiastic of her city that she never misses an occasion to give you all the information you need to discover all the treasures and secrets of Milan! I really enjoyed our chats, in particular the English ones! :) The area is not very close to the centre, but easily reachable with the public transports. Also, I suggest the Parco delle Cave where I used to run every day, really really nice! Highly recommended! Enjoy your stay at Lina's!
