Would not recommend it if you are a female solo traveler.
The area itself was quiet and seemed sketchy at night. There were multiple buildings within the vicinity that looked the same - the host should have explained that clearly. Lock and key system was not straightforward (lock used was old, therefore needed a very specific way to open - same for the bathroom door as well, if you're not careful, you can lock yourself in). Listing stated that you get your own bathroom - this is not true, the bathroom is shared. The flush was basically a single piece of string. Toilet itself was very dirty (unclear if rust) despite "being cleaned twice a day", as it doesn't appear that way. Host was not very reachable on Airbnb (until check-in, during which he was more responsive). He is not responsive to calls, which makes this difficult in case of an emergency. Location wise was relatively good given 25 minutes' walk to Colosseum. Room itself was relatively clean. Cheap. Overall, not very pleasant.
