Alice and her husband were warm and obliging hosts. I arrived later than planned for losing my way but they didn't take offence and they did their best to help me find the home (which was finally very close to metro C).
They have also kindly taught me about the various ways to join the city center and we had some nice talks even if we did not speak the same languages! The home was clean, with all the necessary, and a delicious breakfast every morning. I strongly recommend Mom's house if you want to go in Roma, even if you should now that it is a little bit remote from the city center (around 20-30 min to Termini) and at the 4th or 5th floor (but it was not a problem for me).
