This apartment has quite many pros and cons, and I think different kind of people will find the apartment in very different ways. First of all, Paolo is very kind and responsive host. I didn't meet him, but the doorman Mariano helped us with check-in. Paolo answered all the questions fast.
The apartment is big, so my family (5 people) had enough space. The pictures though are not completely accurate. In the pictures it looks more spacious and bright. At the moment there was much more stuff and things in the apartment. Sometimes it was a bit too much, and it felt like the stuff is just stored there. (Lamps, tables, books, pots..) On the other hand, if you are more bohemian type of person you might like it. (But I would suggest less extra things in the apartment, because now they make it look unclean..)
There were 3 toilets, all clean, but like in old buildings the water pressure is not the best one.
The location is good and you can park a car on the streets. (If you find a spot of course, we left our car a couple of blocks away.) The neighbourhood seemed beautiful and calm, there was not much noise in the night time.
So to sum up: if you are traveling with your family or you are a demanding person, you can find things to complain about. If you are traveling with a group of friends and are more laid-back, you will most likely enjoy your stay here.
