Bright sides: close to the city centre, comfortable mattresses, swift wifi, good technological system, first floor, well-equipped bathroom and kitchen, hot water.
Downsides: great difficulty in communicating with the host (both via Airbnb private messages and SMS, considering that we could use the Net only inside the flat with the wifi and that one cannot talk on mobile phone while visiting churches and museums). I had to ask one thing a bunch of times, even before leaving Italy, before receiving an answer and being told that I should have said it earlier!! Furthermore, the porter scolded us because Pierre (the customary tenant) had left HIS rubbish in the wrong place, the patio. Regarding Pierre, we heartily recommend not to let your clothes and bewildering documents in the drawers where guests are supposed to put their clothes. Lastly, cleanliness is poor and only one of the two pillows of each double bed has its pillowcase, the other is without it and dirty. We'd have brought sheets and towels if we had known!
Overall, we're not very satisfied!
