The stay at Monica's apartment was our first Airbnb experience and it was definitely a very pleasant surprise. The flat is recently renovated, consists of a large bedroom and a pretty large kitchen. It is tastefully decorated and very clean; and the kitchen is furnished with all the electronically devices you can need; including a water boiler, coffee machine and an oven. The bed and pillows were very comfortable (which is so important for a good night's sleep after tiring days in Rome! ). The stay in this apartment was by far much more comfortable compared to small hotel rooms that might start suffocating you after a couple of days' stay.
Location wise, it is in a calm neighbourhood, very close to the Vatican. It was nice to pass through the Vatican every morning while walking to the city centre. There are many small markets, bakeries and a Carrefour market nearby. However, it is a little bit far away from the centre and main attractions. The bus line 64 is close to the apartment, but with our experience the buses were often very crowded, therefore we ended up walking to the center (which we enjoy a lot).
The hosts Monica and her sister Federica were very helpful and kind; assisted us immediately with our inquiries (transportation, etc.).
All in all, it was a happy and comfortable experience for us to stay in this apartment.
