A great apartment, so spacious, very comfy bed, great shower (such a rarity in an airbnb!), we had everything we needed. Alessandro was very helpful and available for any questions.
We were a bit unsure of the area at first but once we got to know our surroundings we realised we were walking distance from so many of the sites and that trastevere is such a good area to be in for cafes, restaurants and exploring the streets.
There are a lot of ambulances going past and they can be quite loud so that is the only thing to bare in mind (i think this is just Rome in general though and not unique to this area).
