This is an outstanding location - a true gem of an apartment. There are outstanding restaurants steps away, the porch is gorgeous, and the location is picturesque and perfect. You're close enough to the sites, but the location is away from all the tourists and craziness of the historic district, and it provides a great respite after a day exploring. We were able to walk to all the main attractions without a problem. Some walks, like the Vatican, are a little longer, but the route is right along the Tiber so it's scenic, shaded, and enjoyable. We would absolutely stay here again.
There were appliances and A/C (strong enough given the crushing summer heat), and check-in was easy.
One note: the main bed is two single mattresses pushed together, and they kept sliding apart at night; however, this was minor.
