Lorenzo's place is OUTSTANDING and is one of the best I've visited in terms of cost/benefit. The neighbourhood is gorgeous, and there's the Trastevere village three blocks away where you can take a walk and have a delicious lunch/dinner.
The apartment itself is exactly like the photos and it was warm enough in cold winter without turning heating on. The building is quite and the apartment is fully equiped with everything, Lorenzo even left us some coffee capsules and other stuff.
There were practically no low sides. I mean, if you are big, the shower might be tight, and the TV can be definitely bigger, but that's NOTHING compared with the huge amount of pros this place has.
You are 20 min of walk away of Vatican City and Colosseum, so it's practically the best spot in the city to stay.
I HIGHLY RECOMMEND THIS PLACE, and for sure will come back. Thank you, Lorenzo!
