Luigi's place was (almost) perfect with the exception of the noise.
Let's start with the pro's:
Great central location, close to bus stop, taxi, information center, any and most central sights and attractions (trevi, coliseum, etc). 15-20 min walk. Comfortable space, has a lift. From what I've noticed I think it's an office space turned home or vice versa. Not sure it's mainly businesses in the building but the building itself is very quiet.
The problem with noise is the window in all of the rooms do not shut tight (close properly). So sounds from the busy street (carts, luggages dragging on the cobble stone all hours of the night) and the chatty police officers (back of building where bedrooms are has a police station opposite (safety PLUS) will wake you if you're a light sleeper. Which was sad because the place had everything but we could not get a good night's rest at all.
The place is huge, be mindful of the 3.50 euro tax per night per person - it is not included in the Airbnb cost.
You will have the entire place to yourself, with AC, tv, towels, almost all the amenities you need. You can buy groceries and cook.
.
All in all it was an good stay. If window/noise issue gets fixed I would definitely stay again.
The bathroom is amazing and everything was exactly as pictured.
I made the noise issue known to Luigi, so hopefully it's fixed in time for the next guest. Just be sure to ask in advance before booking if you are a light sleeper.
