We spent a week in Cedro Apartments and had a really good time.
The two bedrooms are spacious. The beds are comfortable and the air conditioning works very well. Noise from the streets can be heard easily, despite closed windows.
We used the kitchen only for breakfast every morning, I think it would be a challenge to cook anything there.
The bathroom is tiny, but very useable. It takes some effort to share it with four persons.
Trastevere is a very nice area, it is easy to walk to the main sights from here. There are a LOT of nice restaurants and cool bars in the neighborhood. Public transport is also easy to reach.
