We lived in the apartment with my family of 4.The apartment is well done and centrally located. The view of the Duomo from the living room is fantastic. The bathroom and the kitchen were also good. The best part of the apartment is its location.
But the apartment lacks the bare essentials in the kitchen (no food item is available - like sugar or salt for a quick breakfast). Also there were no essential soap and a bare toilet tissue roll was provided. Imagine reaching the apartment and rushing to a supermarket to stock on handsoap, sugar, salt other than getting bread and milk. However, they were generous with towels.
The wifi connection in the house was extremely poor as it was shared with another room.
Did not get to meet the hosts. Also any communication on the cell phone number provided did not work - we left messages for more tissue rolls and stuff...there were no replies. Finally got around communicating through airbnb mails. With a low wifi connection, it was very troublesome. Imagine, we were struggling to find out whom to leave the house keys with when we had to check out.
