Flat is nicely located to the train station within walking distance to all the things you want to see in Rome.
Busses also go directly to the city center.
Flat have everything you need but the walls are very thin. If the people living around you is watching TV then so are you.
Kitchen is well equipped for cooking but have no conventional oven, only a microwave oven. The dishwasher in the kitchen smelled moldy from being closed too long, and there were old moldy smelling floor cleaning rags below the kitchen zink.
Water heater stopped working during our last day of staying and with the slow answer rate from the host we didn't bother with showering before leaving for the airport the next day.
Flat was a bit dusty and the floor below the bed had not been cleaned with old rags laying around.
