This location is perfect for someone looking to experience the less touristy part of Rome. Its a 5 minute walk to Piazza Trilussa, where there are always cabs to be hailed, and its usually around €7-12 to get into the heart of the city from there. Also there’s a nice running route along the river that can be accessed from the bridge across the street.
But if you want to hang out around the apartment and Trastevere (which you should-its the Brooklyn of Rome imo) there are some great bars and restaurants (try Mimi e Coco for pasta or Ma Che Se Venuti A’Fa for a great soccer bar that has some pretty good craft beer for EU/IT).
Ekaterina was helpful and responsive, and the apartment was spacious and relaxing, with very comfortable bedding and chic Italian decor. This is a great place.
