Almost everything about this place is perfect.
The style is contemporary and fun. The floating staircase that wraps around and up to the loft also gives you access to the pseudo-balcony. This isn't good for much besides looking over the incredible street below you. The kitchen and bathrooms are convenient enough to suit average needs.
The location is perfect. Being in Trastevere is wonderful. You are set apart from the insanity that is found in central Rome but you are just a few blocks away from it all. The proximity to the Tiber River was excellent for going on a morning run, no matter how far you're going. Any direction you head in when you leave this apartment, you will find a quaint square within a few blocks.
Alice was also a perfect host. She was very communicative and helpful with letting us check in early to drop off our luggage. She ordered a driver for us from the airport to the apartment. She went above and beyond in so many ways.
The only issue I had with this place was that the tub is practically nonfunctional. The water only comes out of the shower head, it will not come out of the tub downspout. The drain clog doesn't create a seal, therefore letting water slowly drain out. And the jets were filled with mold. There was black mold in a couple of other areas in the bathroom as well.
But as long as you're not planning on using the tub, this place is absolutely incredible and I would definitely recommend it.
