Really cool apartment in a great area! Tons of great restaurants and bars in the Trastevere neighborhood. Close to the Tiber and close enough to the sights that everything is walk-able, yet tucked away enough that you don't feel like you're in a tourist trap area.
The apartment is beautifully designed yet comfortable. Gorgeous wood-beam ceilings and comfortable seating. It's 2 floors (walk up 1 flight of stairs to the start of the apartment), with living room and kitchen on the 1st floor, bedrooms and bathrooms are upstairs. The bedrooms are nice (though the beds and bedding could be more comfortable). The bathrooms and finishes are very nice, though the shower stall is a bit tight. The kitchen well-stocked with all the necessities and the projector TV screen is a cool touch. Both the projector and the TVs in the bedrooms are old, so don't expect to hook up anything via HDMI cable. The internet doesn't work well upstairs either. But who needs it! You should be out of the house exploring Rome anyway.
Only semi-drawback is that it definitely got loud in the apartment at night (per the other reviews), especially if you are sitting in the living room or sleeping in the king bedroom. There is an open storefront restaurant that serves late night food and beer, so it pretty much never quiets down at night. Might be good to get thicker sound-cancelling windows in the apartment. This is a popular area for locals and visitors to go out at night, so grab some earplugs and stay here anyway.
Despite that, this apartment was a great value for the amount of space and location you get in Rome. Highly recommend it! The owner provided espresso pods and wine, which was a huge plus. They were also super easy to coordinate with when we had questions. Would definitely stay here again!!
