Great location . Close to the transit ATAC and just next to the airport. Remember to read all instructions before accessing the apartment. ViKey is a must download on your phone. Gabriella and Frederica were super helpful. We did take the Cotral bus from the airport to Lido de Ostia. You may need to ask help to identify the bus stop at Terminal 1 entrance 6 area. Costs EUR 1.30 and you must buy the tickets before boarding and validate at the door. We have also used Moovit (thanks to Gabriella) and MyCicero apps to navigate the transit system. We bought a 3 day pass and used the QR code on the ATAC (Roma transit). Note that MyCicero might glitch once in a while and you need to sign in several times. There is a a QR code scanner with a +B sign. Don’t try other bays. Overall the trip was awesome and thanks again to Gabriella and Frederica. They really made a difference.
