I highly recommend Lorenzo's place. This is a very lovely apartment situated in the heart of Trastevere. A very lively neighborhood, with lots to do around-the-clock, but the apartment remains pliantly quiet. There is a large private terrace on the same floor as the flat, which is perfect for both breakfasts and dinners, and overall relaxation after a day of sightseeing.
The place itself is beautifully furnished. It has everything you might need - from fully equipped kitchen to two separate bathrooms, as well as a washing machine.
It's in walking distance from all of the important landmarks one needs to see, making it prefect for anybody who wants to visit this amazing city.
Lorenzo himself is a very lovely host - welcoming, reliable and flexible. He went above and beyond to make our stay pleasant. Very easy to reach and fast in his responses. He has made a lovely itinerary for the neighborhood, with places to eat/shop in small radius of the flat - extremely useful for first time visitors of Rome (I recommend the take-away place right next the entrance of the apartment building).
We had an amazing week in Rome and we will definitely come again.
