We had a great time in Rome.
Maria's apartment is charming and mostly comfortable. We were there in August so of course it was incredibly hot and the AC wasn't very good but some cold showers in the luxurious bathroom helped.
The location is very convenient for accessing public transport and it is close to many places you will want to see, such as St Peters. There are lot's of restaurants near by and also shops in case you prefer to prepare your own food, the apartment has a small kitchen to do so.
It's well priced and has all you need so we highly recommend this listing, but we also recommend being organised and prompt in communicating check in with the host.
