Marta was an excellent host! My boyfriend and I got lost going to the apartment and were three hours late for check in. Marta still waited however and didn’t charge us an extra fee due to our special circumstances. We thought we could get by on the free wifi at cafes and restaurants, so we did not arrive with an international data plan. I HIGHLY suggest you DO NOT ARRIVE WITHOUT A DATA PLAN. The place is very hard to find without google maps, especially if you have not been in trastevere before. Even if you get a sim card in Rome, it won’t activate until 24hrs after purchase. So please, do yourself a favor and have international data set up on at least one phone before arriving. Once we got to the apartment, Marta was very helpful and showed us everything we needed to know. She also gave us many suggestions for things to do and places to eat before exploring the city. You will have a fabulous time here and stay in her airbnb!
