Dear future guest,
It's been a while, since we got back home after our stay in Francesco's apartment. Now, it 's high time I wrote something.
To cut a long story short, these are the main insights that might help you:
1) Francesco is a very kind person. However, you shouldn't wait (as someone complained) until he provides you with something you want. He cannot read your thoughts, thus, at first, you need to ask (for instance, to change your towels). When asked, he will do that ASAP, trust me.
2) You need to rely on yourself when planning your stay, locations to visit, and means of transport to select, as Rome is a little bit tough to get adapted to (transport, fraud etc.).
What I really advise you:
a) to go to Rome for more than a week during last days of August and first days of September. The strees are not so overcrowded, many free options are available (last and first Sundays of the month provide you with many opportunities to visit Colloseo, Roman Forum and so on).
b) Also, I advise you to buy a CIS ticket for public transport (25 EUR and all the means of transport through which you can get anywhether you want be it Vatican or Trevi). The one can be bought on the subway (Mirti station is nearby Francesco). It is likely that when you are in Rome, the C line is finally finished, meaning that you can get through the line directly to the city center. Alternatively, you can take a 548 bus near Francesco's apartment and get to the line A (it heads to, in particular, Vatican and it may be convenient for these purposes). Still, getting from Francesco to the city center takes up to 40 minutes if everything works properly.
c) to download a Rome app (any of them) and pay for the full version. You will get the offline map of Rome with the indicator of where you are, full list of sightseeing places with their history and so on. Pop Guide is also cool to be bought when you attend St. Peter's Basilica
Enjoy yourself. Francesco, thank you again!
