We had a great time in Peppe House, where we stayed for a week at the beginning of March 2016. The apartment is just like the pictures: it is light, comfortable, clean and very spacious (bigger than you would expect). On the Airbnb Website you can see the actual pictures of the view from the balcony, where you can drink your coffee in the morning sun. In the living room is a big flatscreen TV. The kitchen is well equipped, with a good (N-)espresso coffee machine, oven and gas stove, etc. Giuliano was waiting for us upon arrival and explained which trambus to take and how the keys work (pay close attention: there are separate keys for the door to the apartment, the front door and the gate). The shower does become as hot as you want, if you turn the knob totally to the left (same system as in the bathroom sink). You can hang your laundry on a drying rack on the balcony. The stop to Tram/bus 8 (Largo Argentina), 3 (Piramide), and H (Termini) is a few minutes walking. Supermarket Simply is around the corner. The neighbourhood Trastevere and Testaccio are very nice to just walk around. We enjoyed a nice night out at a restaurant close by (Buffet and a Rock band): Rec 23 / Emperioclub, piazza del' emporio, check their website. On our last day in Rome our plane left at 6 p.m. and Giuliano was so kind to let us stay as long as we wanted, because they did not have another guest arriving that day. He is also very quick in his response to our messages.
I would recommend this apartment to anyone who wants to spend some time in Rome, in a safe area, close to all the highlights of the eternal city.
