Our flight got delayed due to airport transit -- we warned Marcello as soon as we knew about it, texted him just before takeoff and always kept in touch after landing, and even so Marcello found it fair to suggest we give a tip to his friend who received us and checked us in. Otherwise, he was very communicative and even suggested us a pharmacy once he knew we were looking for one upon arrival.
As for the accommodations, they were as described except:
You can't tell from the pictures or the description that the apartment doesn't get much natural light. If you're planning on saving some money by having lunch at the apartment, know that it won't be very confortable. For dining, however, it would actually be quite cosy were it not for the single-burner stove -- which isn't the one shown on the pictures and limits your cooking options on an already small kitchenette.
Some of the kitchen utensils weren't well scrubbed, so we had to do it ourselves before cooking. Otherwise, the apartment was tidy.
Sleeping was confortable although the building stairs give off light that enters directly through the apartment window and the steps are clearly audible. Not enough to gravelly disturb sleep, however.
Your money will mainly pay for a cosy retreat to sleep at and a central location on a street and neighbourhood filled with commerce.
