Very good communication with the host, Chiara. She arranged a check-in time that correlated with my flight schedule., even though it was on friday morning, outside the normal check-in time.
The flat itself is located directly at the historical center, only 5 minutes by foot from the da vinci science museum! There was everything one needs available in the rooms, really everything :) The whole flat was very comfortable and nice.
I would totally recommend a stay at her place!
