We had a great stay in the apartment. First, location: you are very, very
close to Termini station and to a very nice area of restaurants and shops.
Within walking distance (20 min) to Coliseum, but at the same time, easy to
get buses to go anywhere (since Termini is a final stop for many bus lines).
The apartment is small, and it does not give to the street (although there
are some windows with natural light) but this was a bonus for us: we heard
very little street noises during our stay, and no problem with neighbours.
AC was great: one for each room, they can be regulated indepedently, a must
for Rome in the summer. A small kitchen, but if you are in Termini, you don't
need to use it, there's enough good and cheap options around! We had a problem
with the WiFi though -- we couldn't solve it by chatting, and when we left the
owner came to try to fix it. They kindly allowed us to leave our luggage a few
extra hours at the property, since we had a late plane. We are very happy with
our stay. Thanks!
