Ilaria's location was great, being within walking distance of most key locations in the city, or, within easy public transport. The apartment is large, and while we didnt get to use the outside area due to rain, every now and then when there was a break in the storm, it was still nice to stand outside and enjoy the view. The neighbourhood is historical, and can seem like a bit of a mish mash, but everything you'll need is nearby, especially good food and restaurants. With the famous Michele pizzaria less than a 5 minute walk from your door.
The apartment is up a bunch of stairs (something like 8 flights), which is fine if you don't mind a hike, but if you're elderly, or with mobility issues, it may become a hassle for you, but otherwise, the location and size of apartment is great.
The only gripe that I had was with the hot water, or lack thereof. Coming from Australia, being my first stop in Italy, having a hot shower after almost 24 hours of flying was kind of a big deal, and was a let down to not have it, despite communicating this with Illaria. If it wasn't for this, it would have been a perfect stay.
