Everything was great at Sofia's place. We had a wonderful time there. Sofia was more than helpful with everything we needed. We were able to leave our luggage in the house before official check-in time and also after check-out. The house was sparkling clean and had everything we needed. The place is very close to The Colosseum (about 10 minutes walking) and from there it is very easy to see all of Rome by foot.
On our last day we went to eat at the place Sofia recommended (Cannavota) and it was the best food we had eaten in Rome.
When you arrive at Sofia's you can find a guide book with everything important you need to know for your trip, like: how to get from the apartment to every Airport in Rome, where you can find the nearest supermarket, hospital or pharmacy, where you need to get of the Metro for different landmarks. I found that very useful.
So, I you want a modern, well equipped, clean and central place to stay while in Rome, you should choose Sofia's apartment. I sure will for my next trip to Rome :)
