Travestere is a good base for seeing Rome. We walked to most of the sights and used the tram and buses when it was raining. You can take a taxi from Travestere rail station to the apartment or walk 10mins after a short tram ride from the station. €8 fuimicino-travestere by train. Frederica is a super host and will help you with everything. You will have 40 steps up to the apartment.
