The best! Lucia and Alessandro went above and beyond. Excellent communication from the beginning, and quick to respond. Our flight was delayed several hours, and Lucia got our train tickets for us and emailed them. She sent great directions as to how to navigate. When we arrived, Alessandro met us and took our luggage up and explained how everything worked. The flat was amazing, and he had stocked it with all kinds of goodies for us. The beds were extremely comfy as well. He also typed up details about the city, and places to go and see. Alessandro was readily available during our stay, and never acted bothered when I would ask him questions. He even brought me medicine when I got sick, and called taxis for us on several occasions. The level of service that was provided by Alessandro and Lucia was on par with any 5 star resort. They made our stay that much more enjoyable.
