Excelent appartment, superb location. Enrico replied our questions in minutes. The problem is the bulding. 30 floors, 10 appt per floor and only two elevators; one of them out of use on our arrival's date. Around 20 minutes waiting to get in. Besides that, there is like a military regimen in the bulding: check in is at 4pm, no earlier. So, a large row is waiting to perform it. Then, if you come with a car, there is another step to register it and to pay the parking. Another 15/20 minutes.
Last but not least, check out time is at 11am, but starting at 9 am, different housekeeper knocked the door asking us if they can start cleaning the appt.
So, be patient and come with a lot of time
