Andrea's place was just perfect for what I needed for a weekend in Rome (sport events). I came pretty much late the first night (1am) and Andrea waited for me (24-Hour Check-in).
The distance of the entrance to the metro is just some 100 steps away and it is also something really important (when coming home late or tired, no need to walk much, no need to wait for tram or bus, or pay for cab...).
In case you arrive too late for metro (M1), there is a bus N1 replacing it after midnight departing from Termini station...
Andrea was very helpful and friendly and patient with my requests.
