Host was quick to respond to questions. The front gate to the place was difficult to open that passerby probably thought I was trying to break in… But another key was given the next day and thought it was still fussy to open it did a better job to open the lock.
The area is near to the metro and is around 7 minutes away. It’s my first time to Italy so the loud vehicle/emergency noises during nighttime was a surprise but I didn’t let it affect me too much - just learned to tune it out when trying to sleep. But I’m sure it would be a big problem for light sleepers so make sure to bring earplugs!!
