The flat we rented in Trastevere was absolutely gorgeous, very clean and made us feel at home right away. It's very close to the center thanks to the tram station nearby and to commodities such as groceries store and train station. Overall, we were very happy with our stay in this flat, where we created good memories.
However, we were a bit disappointed to find the cupboards almost empty, considering we were a lot of people, we were expecting staple foods such as sugar, olive oil, coffee, pasta or rice. It's not much, and it's one of the things that makes your stay a bit more hearty.
That said, we were 10 people staying and, according to the airbnb ad, there was enough bedding for 10, but there actually wasn't. Two persons had to sleep on the couch, even though they had paid 6€ for bed sheets.
In addition, the person in charge tried to make us pay the 3,50€ city tax for one more night, on the pretense we had booked until Friday, which we hadn't, and we were able to prove that easily with the emails exchanged with the owners.
The extra charges such as linen and the 3.50€ city tax weren't included in the price or the ad, we only learned about that once we had paid for the flat, and it didn't feel really fair to let us know afterwards.
In any case, we would recommend the flat for its location and coziness, but we also want to report the behavior of the owners, which almost put a damper on our stay in beautiful Rome.
