This listing is in a great location, close to the pantheon (on that note reference to piazza navona is misleading.
However this on a ground floor in a dark small street and the appartment has no usable windows - it is therefore very dark with no natural light. Quite a mediocre place to stay.
Furthermore beware that the owner charges per night and per guest beyond 2. Something we did not notice on booking and which makes this listing overall very poor value for money. Recommend you pass and find alternatives.
