Villa Leitizia is very good. Its comfortable, extremely clean, spacious and quite. No AC but for me fan worked. The nuns are very sweet and make you feel safe particularly if you are a solo traveller like me. Breakfast is plentiful with tea coffee and hot chocolate! Initially I thought it was far, especially with the heat and going the wrong way but it was perfect once I figured it out. There is a bus Nos 246 or 247 across the road from end of Via Diomeda Marvasi to metro Cornelia which takes like 4min. Once at metro everything you will want to see in Rome is easy. Walk to Cornelia is about 25/30min. There is a supermarket 6min away. In the reception, on the wall outside the office, there is a map of metro and bus instruction. Buy a train pass it includes buses!! There is no Tabacci near Villa Leitiza to buy bus ticket. I loved it, found it peaceful, amazing shower and would love to come back:)
