I don't know how to start. Well at the beginning I met with Veronika's friend fernando who was super nice and helpful which gave me an optimistic first impression than he is available anytime for help.
About the house you go through small street with old entrance which is typical in trastevere area, you have to climb 4 floors stairs(no lift but for me it was ok as in this area you walk a lot to see the nice surroundings), when you get inside the house you will have the big surprise, fascinating apartment vast living room and kitchen, vast 3 rooms with bathroom for each, and the plus is that it has an upstairs terrace looking all over Rome (wonderful to sit in the sun and have a coffee or drink, I mean very lovely I can't describe it).
Overall I'm always traveling to Rome like every 3 to 4 months and definitely this will be the place I will stay in. Thank you guys for all.
