Serena's place was literally next door to the Pantheon. It's about 100 steps away. And less than a 10 minute walk to Trevi Fountain. It was easy to get up early and have either to ourselves for a while. So many restaurants, cafes, shopping etc within easy walking distance. Serena was a great host and check in was super easy. We didn't have to worry about anything our first night. Spumante chilling in the fridge, coffee and pastries in the kitchen for breakfast, and lots of recommendations for restaurants. And it was so peaceful inside the apartment we could become completely unaware of the busy streets outside. Highly recommended!
