Mario's home is incredible and he is a great host! It is very close to the metro station (which was only about 10 minutes away from the main station, Termini), it has cute little bars, shops and fruit markets close by, and it is definitely in a safe neighbourhood.
The flat is clean, well kept, and Mario is a very welcoming host. He also encourages the use of common areas (a wonderful living room, the balcony and the kitchen).
The guest room is also very clean, tidy and uncluttered. There is plenty of space for your belongings. The private bathroom is also very clean and spacious. The flat overall is a sight in itself, very creatively decorated and artistic yet does not feel cluttered.
What I loved about Mario and his girlfriend is they did a great job being informative and helpful, yet also allowed us to have our space and did not make us feel like we were in the way.
Thanks Mario :)
