We just loved Bologna, and will return as soon as possible.
I can really recommend to stay at Robertos flat. Super clean, nice and convenient! Close to everything happening in the city, and at the same time in a quiet and calm area. There are several really nice cafés in the neighbourhood, perfect for an early breakfast or an afternoon tea.
Roberto was a perfect and really service minded host, and he did really everything for making the stay easy for us, making sure that we should be satisfied. Which we of course were!
