Elsa is lovely, check in is really easy. Can either take the Metro from the Train Sation or the 85 bus to the stop just round the corner from her house. Walk up a few steps and it's clear to see, has 2 gold plaques on the ground and press the buzzer and she will let you in. She speaks little English but then I don't speak any Italian so I cant really complain, everything she was saying was understood by myself and my partner about the keys, doors and bathroom ect. We stayed in her room without a balcony which was fine and windows opened wide.The first night we stayed thr air conditioning unit was at the door and was pumping out lots of hot air (not ideal) so was a very uncomfortable night sleep for us but we messaged Elsa and she sorted it for us straight away (putting it by the window) so the night after that was more comfortable.
