Emanuela's sister was very kind in greeting me and making sure I knew how to get to the unit in the large building and apparently even alerted the custodian to be looking for a lost person (me!). The apartment was cozy and just what I needed to do my own cooking too. The balcony was lovely to just sit out after a day of walking and have your own aperitivo.
The location is really close to bus stop to take you to into the center; the train station is an easy 10 minute walk which can also take you to the center and directly to Roma Termini. Be aware that the apt is in the south end of Trastevere. There is a supermarket so close to the building it's almost attached to it. The closest sit-down restaurants are a bit of a walk, but you really wanted to eat in the main part of Trastevere, didn't you? :)
