Mauro was a good communicator and a friendly host.
The location is excellent if you are interested in exploring the University district in Bologna, including great cafes (ComixCafe!) and restaurants, or if you are using public transportation around town there are bus stops all along the main street for several city buses.
However, the stay itself was less-than comfortable for a long list of reasons that have to do with maintenance and cleanliness. Worst were bad smells and obvious bedding burns despite it being a non-smoking room, dirty towels, bare minimum of basic supplies and empty bottles of used supplies left behind, plus some other minor inconveniences.
However, we brought our own towels and soap and kept the door to the bathroom (the smelly room) closed. It was not a **bad** stay, but it was one of our least favorite stays after years traveling the U.S. and Europe through Air BnB. Because we are prepared (and easy-going) travelers, we still had a good time. Vacationers who require the stated amenities to be available and plentiful (although there is a farmacia nearby to buy supplies) or who are sensitive to smells may be less comfortable than we were. Note: the place has air conditioning, but it is what I call "Italian-style AC", meaning that it functions but it does not cool the room below about 85F (30C) and does not work quickly. I found this common around Italy, and it was cooler than outside during a major heatwave (yay!!) but especially American travelers expect high-power AC may find themselves hot and grumpy during high summer.
Overall it was an okay stay, but we were relieved it was only a short 2-day stay.
Running an AirBnB is hard, and it takes practice to find out what works for your guests. Mauro seemed helpful and kind, and I think most of our problems could be easily fixed for future guests.
