LOCATION, LOCATION, LOCATION! Smack in the middle of Transtevere, we loved it. Noisy, but that you need to expect here. Nice with a veranda. Its a bit worn down interior, could need some upgrades. We are a family that spend some time indoors, and this appartment didnt invite u to stay much time indoors. The kitchen could need a bit more glasses, wineglasseds and a toaster. Again, most guests just sleep here i guess.
Communication with the host was bad (to our standard). We had to contact AirBnb to get in in touch. After they helped, everything went smooth (had noe heard anyting from the host 4 days before arrival, and after sending message in app, sms and tried to call).
But we do recommend it if u want to stay in Trastevere. Just walk down the stairs, and u have a nice cafe, good restaurants and bars within meters.
