As a frequent Airbnb guest, I had two unexpected moments:
* after I booked, I was informed that late check-in (after 10 pm) is charged additional 50 euros!
* right after arrival, I had to sign a contract for a 3-night stay!
Other than that, I had a good stay. The host is very responsive, the location is next to the subway and within walkable distance from many attractions, the apartment is equipped with everything I needed for a short stay, wifi speed was good.
