Thanks to Matilda's exact description of the location, I was able to find her place in no time. Although I didn't met her in person, getting the keys for the apartment wasn't difficult. Getting to famous landmarks like the Castel Sant'Angelo, Pantheon, Vatican etc. by foot was easy, so I could explore the vibrant culture of the Eternal City. I definitely would recommend you to take your time off and stay a couple of nights at Matilda's place! Thank you for your hospitality!
