Claudia's place was an absolute joy to call home for the three days that we were in Rome. It is only a 10 minute walk to St. Peters Square and centrally located to explore all the different restaurants and cafe's in between the apartment and the Vatican. Claudia provides a very clean environment and a quick response to any needs you may have.
Travel tips: Parties larger than 5 can pay a flat fee for a shuttle to drive you into Rome. It's approximately a 30 min. drive from the airport and we only paid 12 euros per person. The other alternatives were via bus or train, both being over 45 minutes and either more expensive or time consuming. You can find drivers as you exit the baggage claim area towards the street.
If you are visiting the Vatican/Sistine Chapel/Coliseum, buy your tickets online! The lines are huge. St. Peters basilica is free. You just have to wait in line. Also, if you are interested in seeing the Pope he gives an outdoor mass every Wednesday at approx. 10:00am. in St. Peters square. I was not aware of this and it was quite a treat for my Catholic parents to see "Papa".
One last note. The elevator in the building is very sensitive so be sure to close both doors completely! If you don't the elevator will not operate and will stay on the second floor (Claudia's apt.) and you will have an irate 80 year old Italian woman yelling at you like the inconsiderate step child she thinks you are after climbing the stairs to get to her apartment!
I would definitely return to Claudia's place the next time I stay in Rome.
