I really enjoyed my stay at Matilda's apartment. In a super central location, just off Campo de Fiori. Matilda wasn't there during my stay but was always easy to reach on WhatsApp when I had questions. There was a small kitchen with a Moka coffeemaker, and other essentials (pots,pans etc.). If you don't want to cook yourself, there are plenty of options not far from the apartment. Only downside was that my room faced another wall which made it a bit dark.
Overall, however, I really enjoyed my stay.
