Leonardo is an awesome host, always willing to help. He gave us nice tips about the city and sightseeing. The location is quite central and is in walkable distance to the main street.
The apartment itself was clean and cosy, though a bit small. It had everything we needed and even more. The only "disadvantage" of this apartment is the 4 flights of stairs, and no elevator in the building. But that's what we knew before the booking, so no problems with that.
I would totally recommend Leonardo's place.
