Had a truly lovely stay at Laura's house. Her flat is in a central location (just 3 metro stops away from Roma Termini station and good metro connectivity to the usual tourist spots) and has rooms much larger than the photos show. Her kitchen has everything you need for breakfast and she is always there to help.
Laura's was the one place we truly felt we were living in an actual house. You can see her interests (history, art, books!) and her life everywhere in the house and she herself is extremely friendly. You can look forward to nice conversations with her if you have the time. :) There is a sense of warmth, genuineness, and love in her words and actions, something that you otherwise get only at home.
Things you should keep in mind:
1. Shared bathroom - not such a big deal as there are two bathrooms
2. Four nice cats (my son loved them and still talks about them!)
