Marco's is a very nice, helpful host and his place is very close to the center of the historic quarter. The apartment is in a historic building up three flights of stairs and has beautiful very high, wooden ceilings. The place is smaller than it looks in the pictures (it is a studio with one tall window/door to a small balcony and an attached small kitchen and bathroom). It is clean, although the pillows had some stains and the bed sheets had a few small holes in them. The upstairs neighbors were walking very loudly (and moving furniture?) at times at night, and the apartment is located in a mixed neighborhood near a small park that sometimes felt unsafe because of a few groups of men hanging out there. But it was terrific to be a short walking distance from some of the best sights to see. Marco gave us very detailed recommendations. Grazie, Marco!
