Me and my fiancee stayed for three nights here. Alessandro's place is fantastic! The room was clean and stylish. But the shower is small, so if you don't want to get your hair wet, invest in a shower cap.
The only con is noise. We could hear everything in the apartment, but we had no city noise luckily. I will say our neighbors were early risers (at 4:30am) and we are night owls. We could hear very door open/close, every pot and pan, and their conversations. So if you get up early this is still a great spot! If you are night owls like us, maybe try to leave a message on the other doors or in the kitchen. We never actually met them so it couldn't be resolved.
Alessandro really knows his stuff! He was very helpful and his food suggestions were great! He gave directions by bus/metro into the central. I would add that you can totally walk the ten minutes to tram 8, instead of taking a 3 minute bus like he suggested. But walking is not for everyone. Other than that tram 8 is great! Also we decided to buy individual bus passes for 1.50E each instead of a 72 the bus pass (spent 15E for two people instead of 36E) If you are like us, you head into center, stay there and do not head out till sunset. Everything is within walking distance in the center so you don't need a bus to catch everything. But if you want to head back home each midday and then go back to the center, get the pass.
I would say be careful of taxis. Try to get the mytaxi app so they don't overcharge. We had one driver (we highly suspect) take the long route home, costing us 22E at 10pm. But another took us from Trastevere station to Rome Termini (a longer distance than the above-mentioned) and it was 12E at 6am. So just be prepared.
Otherwise great place!!! We will be visiting again!
