We had such a great time in Rome.
Theo's place is as in the pictures (perhaps even better) high ceiling makes it more spacious and roomier than it is, very clean and having an aircon on the hottest day in Rome is a blessing.
The location is very central and everything can be easily reached on foot (or by bus), very close to Vatican city, a lot of place to eat and hang out in the neighborhood.
Upon arrival Theo explain us everything and arranging someone ready by the door to hand over the keys to us and even helped us with our luggage (thank you Andrea).
A small note if you are planning to stay at Theo's place make sure you ask him in advance how to check out and where to leave the keys, as we have some trouble with it and had to wait for one hour before we eventually are able to leave.
Other than that is definitely an amazing place worth to (re)visit.
