My friend and I (two dudes) stayed at this airbnb for three nights. Here was our experience:
Pros:
1) Convenient location -- very close to the Colosseum and restaurants
2) Comfortable bed
3) Very cool waterfall shower
4) Washer and dryer
5) It was clean
Cons:
1) The "sofa bed," which I slept on, does not fold out into a bed and is only a sofa. It was way too small to sleep on and not comfortable. Having a sleeper sofa was a big reason I booked this airbnb, so I felt misled.
2) The noise level outside the airbnb is extremely loud, because there are restaurants nearby. Every day, you can hear people talking outside until 1 am. One night we stayed, we heard a piano playing outside until midnight. This made it difficult to fall asleep, though I recognize that outside noise isn't technically the airbnb host's fault.
3) There were maintenance issues with the airbnb, which we discussed privately with the host. Not a huge deal but a little annoying.
