Advantages:
Location - not far from the city centre and from the metro station, beautiful European district.
Apartment - everything you need even for a long stay.
The host - Paolo gave very exact directions on how to get to the apartment .
Disadvantages:
It is not clear whether the room was cleaned before or not.
To be on the safe side I changed the bed sheets myself.
The second night I returned to the apartment and one guy was taking my stuff out of the room!
I was shocked but we spoke and decided the problem. He took another room. By the way, there are three rooms in the apartment and only one can be locked. But everyone has key to this room.
The next night someone was trying to enter my room at night. Thanks god I locked it from inside. But it woke me up and scared. It is very unsafe and unpleasant. I don't know how is it possible to leave sth in the room if everyone can enter the room at every moment of time.
Finally the host wrote me at 3 am to ask leave the room in the total order and I did it. But he also asked me to leave the keys in the lockbox which is on another street and it was unomfortable because he didn't tell it in advance and in the morning I was in a hurry to the airport.
So, the apartment itself is really good, but you can't fell safe and there is no any hospitality at all.
