My husband, sister, and I spent a lovely week in Silvia's apartment. The location near Santo Spirito was just right between close to major sites but also in a quieter local neighborhood. I have never stayed in a hotel or apartment in Italy before with such amazing air conditioning and water pressure!!! (esp. given the temps near 100F/37+C)
Silvia was a wonderful host. She was easy to reach when we had flight delays for check-in. Most importantly, she saved us from a taxi strike by taking us to the airport VERY early in the morning. Can't recommend this location enough!
