I stayed here for 3 nights. The best part of this house is location. Everything is at walkable distance. Host are two nice girls who are helpful in providing direction to tourist attractions.
However, since you can't locate the house on google map so, it needs some roaming around and asking for directions from locals, specially name of streets. Though, I must mention that she provided me written direction from Rome airport to her house.
House is clean but as mentioned in the advertisement, it's a very old house with loud street noise. Noise doesn't stop until 2 AM in morning. Since house is old so, it makes all creeky sounds when you walk around and bathroom is very very small and bit scary. Also, floor is supercold, so better carry your bathroom slippers, as host doesn't offer it. (Generally it is provided at all private rooms on airbnb, I visited so far.)
House is also very cold. Since, host always stays there so they have got used to it. I must mention that they should get thermostat in house to get the temperature in house. I think it was 10-15 degree centigrade. On first day I put the heater in house at high mode and next day I was asked not to put it at high because it becomes uncomfortable for host, which I duly obliged. I would request them to get a portable heater for guest room. For guests it's important to get a good night sleep after tiring day around city sightseeing. I could not afford a good night sleep due to low temperature in house and loudness on street.
I would never like to stay here again, even though host is nice and helpful people.
