Stay at Claudio's place. You won't regret it. Claudio is an outstanding host in every way from the first day to the last. His apartment is a little far from the city centre, but it's located in a really safe and nice neighbourhood with all the necessities within a very short walking distance (go for the cafes directly downstairs or just down the street!). His apartment is also right next to a tram station so it's really convenient to get around.
The apartment is really clean and the room is spacious and comfortable with a nice view over the neighbourhood. Right now it's getting really warm in Rome but Claudio thoughtfully provided me with a fan which really helped with the weather.
The best part of my stay was experiencing Claudio's hospitality. He clearly knows and loves the city inside out and can give you so many tips on where to go and what to do. He's also the kindest, most welcoming host I've stayed with so far and really goes out of his way to make sure you enjoy your time in Rome.
Thank you for showing me how warm and friendly Romans can be, Claudio! Looking forward to coming back soon :)
