Helene was wonderful in so many ways. Her apartment was in a good location, walking distance from almost any historical or tourist spot you would want to go to. The apartment was modern, clean, with most amenities you might want. There is street noise of cars driving by, but we've found that to be the case in most Airbnb rentals we've had in Europe, particularly if you want to be in a central location.
Helene met us at the apartment and told us where the grocery store was (two blocks, very close). She arranged for a driver to pick us up and return us from Linate airport. More importantly, she went way above the call of duty when, first, we lost power on a Sunday morning, and she talked us through where to find the main circuit breaker and to turn it on, and then, second, when one of us suddenly took ill and ended up in the emergency room all day (the day we were checking out of the apartment and she had new guests coming), she arranged for another room in the same building since we missed our flight and had to stay overnight. Truly top notch service!
