The apartment is spacious and light-filled, and I enjoyed the furniture and decoration.
Lorenzo and his wife were kind and efficient checking me in, with good communication when I arrived.
Sadly there were some problems: I think the previous tenant had been a heavy smoker, and the apartment needed airing out. Also, as another reviewer noted it was quite dusty - I think it has been empty a long time during Covid. Sadly these things weren't acceptable for me as I suffer with allergies.
The air conditioner is in the living room - you need to leave the door open to the bedroom to stay cool at night. It works, but leaks a lot of water and probably needs replacing. The pillows are quite hard and uncomfortable.
If it was given a good deep clean and a few small updates, it would be a lovely place to stay, ten minutes walk from testaccio and in a lovely building with a great view. I wish all the best to Lorenzo and his wife.
