Elena's place is lovely! She is a very communicative host. Just a word of warning--if you're arriving late at night (like I did) and not from Italy, be sure you have a SIM card ready or roam-abroad(vending machine at airport is eSIM or you can buy online, otherwise actual SIM card need to go into shop) to contact her. There are stairs, so be prepared and be sure read instructions she sends you. It is small so it may not suit taller people.
About a 20 minute walk from Central Station and a few minutes from cafes and restaurants on the main road. Elena does leave snacks and drinks for you and is easily accessibly if you need her. Overall I had a lovely time and would recommend both the place and the host!
