In general, everything was ok. The location is great, the apartment is also good.
But should mention i've expected a bit more information/involvement from the host's side. However, i really liked our stay, would mention a couple of things for those who travel with the kids:
-If you travel with infants please note it is a 4th floor of the building without the elevator. It was tough to carry the baby and the baby stroller so if you still choose this location make sure you travel not only with the kids but also with your partner :) Unfortunately i didn't ask specifically, just if the apartments are suitable for infants. Erika also didn't say anything about that. Also, there are couple of steps in the flat, including open stairs down to some storage (don't really know how to call it).
-we stayed in the apartments in the winter and it was rather cold there. I was given instructions via the text message but it didn't really help, the max temperature was around 19 degrees. I was also informed that the maximum is 21 as per Italian law. But still could not achieve this. It was warm in the bedrooms but always chilly in the dining room, it is big with high ceiling.
