Unfortunately, the cons outweighed the pros and we would not stay here again.
Camilla was a great host. She was quick to respond to our messages and booked us a taxi for our early-morning flight. The location of the apartment is great, it's spacious, and the view of the Duomo through the balcony door is gorgeous.
The problems with this apartment stem from the colony of pigeons and the pigeon coop that is immediately on the other side of the balcony, not shown in the photos. From what we've (now) read in other reviews, it appears that a neighbor (not Camilla) has put out this coop-like structure on their patio and feeds/waters the city pigeons. The result is that, as soon as you approach the balcony door, you see the pigeons and pigeon coop which is so, so gross - it is covered in dozens and dozens of pigeons, feces, and even some dead pigeons. The balcony itself was clean and there are spikes along the balcony railing to keep the pigeons off of the balcony. However, for us, the unsightly coop and the number of pigeons right next to us made the balcony completely unusable. We do feel that the photos and the listing for this apartment are misleading because, unless you read some other reviews, you don't realize that the balcony is unusable. We booked this apartment BECAUSE of this balcony and our dream of having glasses of wine out there in the evening, and did not get that at all.
In addition, because of all of the pigeons, we did not want to open the balcony door or leave it open overnight for airflow. Without the ability to get airflow, the apartment was SO hot. As advertised, there is no AC. I think that would have been fine if we could have opened the door. We did what we could to keep the place cool - closing the curtains during the day, kept the fan on, but even with that, it was incredibly hot. We had to sleep in our underwear on top of the bed, without any sheet on us, fan on, and were still hot. I'm sure this wouldn't be much of an issue outside of the summer months.
I recommended to Camilla trying to do something about the pigeons (I'm not sure if the city can do something about it or not...it doesn't seem like it should be legal...or talking to whoever owns the building), getting screens to cover the door and windows so that they can be opened for airflow without worrying about pigeons coming in, and purchasing additional fans for the apartment since the single fan available was not enough.
