Massimiliano's place is perfect for a single person or small group to call base camp in Trastevere. It's centrally located, very spacious and offers a very nice jet tub to soak after a day full of walking/exploring.
The downstairs bedroom is window-less for those who love to sleep in black-out conditions and offers the only full-bath within the unit. At time's you may hear voices of the neighbours or plumbing noises (shower, toilet flush, etc.) but overall I slept well in the room.
The upstairs bedroom has a window/curtains that offer light in around the clock which didn't allow for my* best sleep, yet the room is very quiet and away from most neighbours.
Breakfast is served down the street at a restaurant (coffee/espresso/pastries). There is only a mini fridge in the unit; no coffee maker or other amenities provided so be prepared to head across the street to the mini mart.
Overall worth the value and location!
