I stayed at Matilda's place for 5 days and her apartment is right near Campo de Fiori which is a great location to be. There is a market every morning and a famous bakery literally on the same street as the apartment. I was able to walk to Pantheon and nearby Tazza d'Oro for great coffee within 15 minute, and all other major attractions such the Trevi Fountain, Spanish Steps, etc. in no more than 30 min. Rome is a very walkable city and Matilda's place was perfect as a home base. The room has a small window which faces another building, so there isn't much natural light but this wasn't a huge issue since I spent most of my day exploring the city and returned at night. I would be happy to return to her apartment next time I visit Rome:)
