Lis Mari's place is exactly as she described it. My son, who is over 1m 82 tall was with my daughter and I for two days out of our 4 day stay and yet we never felt cramped. The apartment is very well equipped, the beds are comfortable, the bed linen and towels are good quality. Lis Mari has a wealth of info in the flat about local restaurants, bus routes etc. Best of all she came with her lovely husband to pick us up at the airport.
The location is very handy for the American University of Rome if anyone is interested.
You are not in a touristy neighbourhood-this is the real Rome-no tourist rip offs. You can walk to Trastevere or take the bus to Piazza Venezia very easily.
