I haven't met Elena in person, but the friend I was travelling with did. Elena has been extremely helpful throughout our entire stay. She has been flexible in meeting my friend instead of me when my train was delayed and very prompt in replying to my messages, whether I was asking for suggestions (restaurants and such) or for even more flexibility (offering us the chace to stay longer on the check out day in order for us to keep our luggage there conveniently). The apartment was extremely clean and functional, with everything you could need, from fruit juice and milk in the fridge, to pots and pans, to towels, etc. The location of the apartment is super: very close to the train station but also very close to the city centre and main points of interest. Me and my friend have walked everywhere, without any need of taking a bus. Last but not least it has been extremely easy to find the apartment. I would definitely recommend this place to anyone who wants to stay in Bologna, even during winter time: the heating works perfectly!
