Very clean - photos are accurate as to what the apartment is like. Location is really great, with only a short walk to the main square, the Mercato delle Erbe, and many cafes/restaurants in central Bologna.
It is also only about 15mins walk from the station, from which it is easy enough to catch a direct train to other cities. Quiet, though the street outside can get a little loud on a Saturday evening.
The host was very prompt with their responses, and was kind enough to arrange an early check-in when requested.
The kitchen is very well equipped, though there was no salt, pepper, or oil for cooking - so please do bear this in mind if you intend to cook any of your own meals.
If you stay here, we would highly recommend Il Cantuccio for dinner. It is a short walk away (around 3mins), a very cosy spot with really friendly staff and many fresh seafood dishes - we would highly recommend the crispy octopus antipasto in particular!
