It’s a very nice place, quiet location and the apartment itself is very clean, bright, and cool because air conditioning is working perfectly. The host is very hospitable and provided everything we need.
If you are coming by public transit, take a taxi, it only costs 5 euros including tips. Don’t rely on your “gps” it will take you to the stairs with approximately 60 steps.
And if you are going to Vatican, this is an ideal place because Vatican is just across the street from the apartment.
