We really enjoyed the apartment. The place is very contemporary, clean and the location is perfect. It is very close to Roma Termini. Also, thanks to Alessandro for accommodating early check-in as it helped us maximize our time in Rome.
The lock and key is a bit tricky, it takes few attempts to get used to. Definitely try out the cafe at the corner of the building, it is open late in the night as well as early in the morning.
