Marii's apartment is great! It has an amazing location within the city center and you can reach anything on foot. It's only 2 mins from piazza Navona and there are many nice restaurants and bars nearby. Also some supermarkets (~1-5mins) if you need to buy anything. As for Marii herself, she is a very attentive and kind host! She gave me many recommendations for where to eat and what to visit and communication with her went very smooth. All in all, I had a great week in Rome and really felt like a local at the end so i can definitely recommend this place!
