My wife and I spent a wonderful week at Daniela's apartment. We loved the space - a very large one bedroom apartment; modern and uncluttered. Her photos do a good job of showing the unit - and the open kitchen / large living room is even better than the pictures portray. We greatly appreciated having the nespresso machine for our morning coffee, too!
Daniela is a great resource and has excellent suggestions for the city (restaurants, markets, etc.). She was very timely and responsive to any of our messages, and very helpful.
The apartment is located in the middle of the historic city center. It is a few short blocks down, and one over, from the Spanish Steps, and an easy walk to the Trevi Fountain. The few blocks help to get you some distance from the heavy tourist streets, while still keeping you very well located.
Due to an injury before our trip, I was using a cane; it was incredibly easy to access (small step to enter the building, easy elevator ride up, and then only two small steps inside to enter the apartment).
We suggest closing the shutters on the bedroom window before going to sleep. The shutters cut the street noise tremendously, and we slept easily with them closed. If you are not a city person, or simply a very light sleeper, you may be a little distracted by occasional cars or voices - but that could easily be handled with a white noise app or ear plugs too. We closed the shutters and had a white noise app at a low level, and slept very well.
We highly recommend Daniela's apartment and look forward to staying there again during our next visit to Rome.
One important tip for getting around - use either the "MyTaxi" or "IT Taxi" app (or both) to summon taxis. You can specify your destination in the app (and pay through it if you wish). In Rome it can be difficult to flag a taxi, and taxi stands don't always have taxis waiting.
