If you want to be right in the middle of the action, this is the place for you. You are literally on the path between the Pantheon and the Trevi fountain. We loved the restaurant right below the apartment. Lavinia (the host) is so sweet and helpful. She speaks perfect English and is available to answer all your questions.
The whole apartment is very nice and comfortable. The bathrooms are modern and the beds are comfortable. The WiFi was fast and reliable.
Do be aware that the noise from the street is loud and goes on until very late. You then have very loud glass crashing and garbage noise before dawn. Lastly there was very noisy construction going on during workweek days. The windows high quality and keep the noise to a minimum, but earplugs are recommended.
