I am a solo traveller who has been travelling urban Europe (London, Paris, Berlin, Lisbon, Amsterdam, Prague) the last two years---staying at airbnb's nearly all the time. My main two criteria in selecting a place are location and a sense that the host will help me stay out of my own way. Flavia and her little apartment succeeded wonderfully on both counts. But then there was a third thing: Flavia's apartment was welcoming, comfortable, homey (and the garden was lovely and the building solid and peaceful): the very thing for an exhausted guy who just escaped from Venice. Flavia was a wonderful host---and, oh, Bologna was pretty neat. too. I should have planned an extra day!
