Unfortunately, it was a bad experience for me.
The air conditioning is switched off from 23.00 until morning every day. I was not informed of this when I made the booking in March 2017 nor was this mentioned when I checked in at 22.00.
Temperatures were reaching 42 degrees celsius in Rome.
When I returned to the apartment on the first night, the apartment was hotter inside then outside (due to the air conditioner being switched off).
Despite opening all of the windows, the apartment was excessively hot and I was not able to sleep at all that night.
I contacted the host (who was not available) and received a prompt from BnBSitter who said that they would look into the matter and have someone come to fix the air conditioner (as well as the shower drain which was not working properly).
In the end, no got back to me until the second evening and on the third day BnBSitter stated that no one would come to make repairs as it was believed that it was normal that air conditioner was switched off at night.
If this normal, then the host should have provided alternatives such as portable air conditioner and/or fans for guests to use when it is exceptionally hot.
As a result, I was not able to stay in the apartment for the remaining two nights and had to check into a nearby hotel
The host offered to refund only the last night. Therefore, I had to pay for the other two nights (one of which I didn't even stay in the apartment due to the heat).
Again, please be aware if you are going to be visiting Rome during hot weather.
Saying all that, the apartment was clean. And it is in an ideal location.
