We were two couples in the 'senior' age range. The apartment is incredibly spacious, light and airy, comfortable beds, perfect for a longer stay (17 nights for us), and located very well in Bologna (just far enough from the touristy things around Piazza Maggiore but just 5 minutes from the Mercato dell'Erbe). Federico was waiting for us outside when our taxi pulled up, and Mattia and Sandra were always responsive when we contacted them (even, with a minor issue, on a Sunday morning). The pictures on the website are accurate, but they don't convey how large the rooms are. Highest recommendation.
