This was my favorite Airbnb I've stayed in all across the world! The most charming and historical - it's 500 years old and was the former residence of the mother of Lucrezia Borgia, and you feel the grandeur inside. The ceilings are high and lovely, and even the old windows make you feel like you're living many centuries ago. The bedroom was large and grand, with sitting chairs and a small writing table - I wanted to spend all day lounging in the bedroom! The kitchen / living area has the same wonderful feel, and the bathroom is large and modernized. Absolutely a wonderful place to stay - the only note is that the kitchen is rather small, and has a stove but not an oven/toaster, which is not a problem but just a note in case you plan to cook a lot. Normally I love to, but Rome is one place where I wanted to eat at as many restaurants as possible!
The flat is perfectly located just off the Campo de Fiori market - it's above Rome's oldest bakery with the most wonderful thin pizzas that we ate every day for lunch. You are awakened in the morning by the smells of the bakery! The area is ideal as you can walk to almost any neighborhood - all of the sights and just across the Tiber to Trastevere. It was so fun to be just off of the lively piazza, and the windows are such that you don't hear the noise at night.
Maria was a wonderful host - we did not meet her but she was super responsive to any email and had an iron brought over when we requested it. I would absolutely stay here again and I really hope to. Grazie Maria!
