The location of "A Casa di Marilù" is difficult to beat. We didn't know the city of Naples, but we quickly realized it. It is a real privilege to descend in the middle of Via Toledo, with the possibility of quick access either in one direction or the other. (We stayed 6 days at the end of November, the weather was unfortunately rainy but the location mattered even more.)
The picturesque character of Via del Formale is guaranteed! ;)) The two floors that have to be climbed up to the door of the residence are not very difficult to climb but the stairs are very narrow, which, unfortunately, matters when you have luggage. The apartment is nicely decorated, the double bed is big enough but the pillows are - I must say - awful!
We had no problems with street noise or neighbors.
To sum up, we can recommend accommodation at ”A Casa di Marilù”.
