Amazing. But this isn't fair to say. Let's start with location and actual property.
Beautiful, clean, and spacious. Me and my buddy stayed for 2 weeks and loved every day it (both 5'9+, 185lbs+). Two separate showers and two huge bedrooms. (it says double bed, it's definitely bigger than a queen). Metro? Right across the street. Metro to colosseum, 6 minutes. Vatican? 8 minutes. Wanna go to the beach in Ostia? Super simple to get to, why? Because you're right next to the metro! The local food that is available to you is walking distance and it's damn good!
The neighbourhood is safe and friendly and you have an awesome coffee shop right downstairs.
The WiFi internet is fast and easy if you need a day to relax and reset from all the walking. You won't go wrong picking this place! Would stay again and again!
Now let's talk about Vincenzo: if I could pick a host to be a friend, it would be him. Easy to communicate, showed the place at check in and provided quick suggestions on places to check out around the immediate area.
I think I wrote enough and you get the idea, this is a place I'd book over and over. If you have a chance to take it. Definitely grab it!
