This is a wonderful apartment located in one of Rome's most sought-after districts. I stayed there for a full month. The apartment is well arranged with a spacious bedroom, a reasonably large living-room(which includes an open plan kitchen), and a nice bathroom.
The flat is tastefully decorated and is very light, with large bright windows that make spending any amount of time in it a true pleasure. It conveys a real sense of well being and elegance.
Concerning practical details, the appliances all work well (good internet connection, dishwasher, washing machine, air conditioning in both bedroom and living room - very appreciable in the roman summer - and good shutters and curtains providing obscurity for the night).
The only minor problems I noticed was that:
1) the kitchen is slightly under-equipped (there are enough basics like plates and glasses and a small number of pots, but not quite enough kitchen utensils - for instance no kitchen knives and no wooden spatulas to cook). If you don't really plan to cook during your stay, this will definitely not be an issue however.
2) Also, there tends to be a bit of noise in the morning (sometimes even very early morning) from the street, although the windows are modern and well fitted.
Altogether though, these are minor problems and what I remember from this place above all are its wonderful location, its high ceilings and brightness as well as its elegance and tasteful decoration. It was the perfect place to spend a bit of time in Rome and appreciate this unique city - I am sure to want to come back again!
