We really enjoyed Simona's Ultimopiano apartment while we stayed in the Trastevere neighborhood of Rome. The apartment was comfortable with air conditioning (necessary, as explained later) and nice bedding. We did not use the kitchen, but it was available if desired. Having two bathrooms, two big beds and excellent wi-fi was a real plus! If you arrive early, as we did, there is an affordable luggage locker business about 700 meters from the apartment, which we used. And Simona can arrange an excellent and affordable driver for private and affordable airport transfers, which was very helpful. We would definitely consider staying here again if we ever revisit Rome.
There are two things that I feel should be reemphasized here, for those considering a stay at Ultimopiano.
First, note that this is a third floor walk-up. The stairs are narrow, with three sharp curving corners (one on each floor). Our two 45 lb. (21 kg) suitcases were tough to carry up and down the stairs because of the narrowness and steepness of the staircase.
The second item to consider is the lovely and lively Trastevere neighborhood. Trastevere has become party central for young adults. On the three nights we were there (Friday-Sunday) there was no holiday nor special event, but the square outside the apartment and the many streets in the neighborhood (about the width of a one-car alley) were jam-packed well into the early morning hours. Imagine slightly less crowds than Bourbon Street, New Orleans during Mardi-Gras! Even though the weather was comfortable enough to open the windows in the apartment, the revelers noise was too loud for sleeping. Luckily, when you close the windows and turn on the air conditioner, the din from outside almost disappears, thus the name Utimopiano. If you do not like staying in the middle of a party town, a weekend stay at Ultimopiano may not be your best bet. Trastevere does have great restaurants and decent access to public transportation.
