The appartament was fine and comfortable, the location was strategical (really close to every monument/point of interest) but there was some minore issues at the check-in such as: unclear indication for the parking spot, lack of notification of the USA ambassy (and the police checkpoint, if you travel by car), lack of notice and instructions of the door alarm, wifi was not working and we have to manually restart the router; last but not least we found two empty cans of beer instead of the promised pilsners in the fridge, shortage of toilet paper and paper towels.
Overall the apartment is great but the absences of communication with the hosts, even by phone, at our arrival was a major issue, especially because we came through a long car journey
