The apartment was as nice as in the pictures, the decoration is tasty, and it was really clean and brand new (we probably were the first guests), so we felt like home.
The location is 10mn walk from the center of trastevere where you can find all the bars and restaurants (really cool area where the Romans go out), so close enough not to be a bother to get back at night.
The exact location of the apartment is not the charming area of trastevere, but it wasn't a trouble, and to compensate there is the advantage of having a low cost supermarket 3mn from the apartment.
We asked for an early check in and were able to put our luggage in the apartment while the housekeeper was preparing it, so it was very practical. And for the check out we were again able to do a late check out leaving the luggage to enjoy freely our last day in Rome. Very enjoyable.
Even if there was no one to welcome us to explain the functionality of the apartment (nor for the check out), Livia was communicating with us by email, and there was a complete book of instructions to help in the apartment.
We would definitely recommend Livia's place for a comfortable stay in Rome!
