Location is really great, just a few hundreads meters to colloseum. Kitchen was fully equipped, so you can prepare food by yourself. There are three A/Cs and all of them work properly. There is also TV with hundreads of channels (there are also some of them in english).
Unfortunately, it is everything from pros..
Cons:
Wi-Fi was not working.
Heaters were not working. It was extremely cold in bathroom in November. You need to turn on the warm water for a moment first to let it heat the bathroom before you can enter.
Bath was really, really small. I am just a 1,85m guy and I had really big problem to take a shower normally. If you are bigger and wider, it will be really hard for you to wash yourself.
There were no pillowcases - it was just a sheet covering the bedclothes. Maybe it is normal in Rome? I don't know, but for me it was strange.
Host was trying to convince us to pay money for damages made before by different guests.
