The flat is on a narrow cobblestone street in an area filled with restaurants and very close to the Piazza Navona. The location is wonderful and the flat was very clean. We never met the host as she had someone else meet us to check us in. She seemed to be in a hurry to get on her way so we got just a very brief overview of the flat.
If you want fresh air from the windows, be prepared to hear street noise from morning to well into the night. To access the loft bedrooms you must ascend stairs with no railings and there are no railings in the loft--just an open drop off so if you are traveling with children this might not be really safe. My husband was worried if he fell out of bed he'd roll right of the edge of the loft.
We could never get the downstairs TV to work which isn't really a big issue since we didn't spend much time in the flat anyway. We also couldn't find shampoo or soap. Some of the furniture downstairs is a little worn.
We really liked the large closet area (possibly listed as a 3rd bedroom?) off the main room that was a great place to store our luggage.
There is no lift and you must climb several flights of stairs to reach the flat.
Overall the location makes this flat.
