Best part of this airbnb for us was Paolo's friendliness and the location. I was messaging him to let him know where we were, and he went out of his way to come meet us. Despite a misunderstanding (i didn't realize he was going to greet us on a busy street so when he originally introduced himself to us, we all just kept saying "no thank you" because we thought he was trying to sell something...oops), Paolo was extremely kind and helpful, even helping us bring up our bags the final narrow spiral staircase. He had bought us some breakfast items such as croissants and jam and juice and little cakes, which was so thoughtful and that definitely helped in the mornings before we set out for the day.
Location is great- right near via Nazionale, a major tourist street with a lot of shops and food. Try the place right next door to the front door for lunch. Sandwiches were delicious! Close to Repubblica metro station, which is convenient for getting to the Vatican.
The layout of the place is a bit awkward for 4 people because one bed is in a low sloping-ceiling room with the only table and the other bed (or rather, a single bed and a cot) are in the room with the kitchen and the access to the amazing terrace. The bed in the table room was comfortable. The single bed in the kitchen room was fine, but the cot next to it was not comfortable. Also, bring mosquito repellent! that's nothing to do with the airbnb but i was bitten to death.
Plenty of towels and heaters worked well. It did take a little time for the water to heat up for a shower, and the water pressure was pretty low but nothing major. The place was very quiet despite being close to so much. Highlight was the terrace, though it was a bit too cold to enjoy for too long.
The description mentions the last flight of stairs. Keep in mind this is a narrow spiral staircase that can be difficult to manage with luggage.
All in all, we enjoyed our stay and especially Paolo.
