I stayed a week in the flat and had an amazing time.
Communciation was easy and fast, check-in and check-out well organised. The flat is has an amazing location in a cool and beautiful neighbourhood, with many restaurants and bars/cafes around. it´s a 15min walk to Campo di Fiori and Circo Massimo (another 5-10 min to the entry points of Colloseum and Forum Romanum). Or just take a bus and tram to get there even quicker.
Flat has a little, equipped kitchenette and fridge to cook / store your own food.
I can definitely recommend this flat, for short- and long-term stays.
