My stay with Mary & Nello was absolutely wonderful. After some unavoidable travel delays upon arrival, they were incredibly supportive and helpful with details on how to get to their space, and helped to make sure things went smoothly. It is always important for me that my lodging is clean when I travel, and their room was absolutely spotless! They provided some nice, caring details, too, like chilled water and snacks, and even had a USB-compatible charging port for my phone-- which was an enormous help. It was a small walk into the city center from their location, perhaps about 15 minutes. But not unpleasant at all, and I found it nice to see a bit more of Bologna while walking. All in all, my time in Bologna was exceptional between the sites, the food, the city, and the people I met. Mary & Nello's room and their hospitality helped make my trip what it was, and I will stay there again whenever I return, if at all possible!
Side note: I was also surprised at how easy it was to grab a taxi from the Bologna airport--truly one of the smoothest taxi rides I've had from a city airport. I arrived late (around midnight) and simply got into the line and took the next available taxi. Didn't need to wave one down or anything, and there were plenty there, even late. A breeze!
