Three of us (adults) stayed in this apartment for five nights. It was comfortable and convenient. Maria arranged a taxi for us from and back to the airport which was very convenient and relatively quick (55 euros each way). This is a cozy & homey apartment on the last floor of a residential building with an elevator, in the midst of a lovely neighborhood full of great shops and restaurants and within walking distance of all the sights. Despite the central location, it was pretty quiet. The streets around are mostly small and narrow but also close to a main road which is convenient too. We ate out mostly but also shopped at one of two nearby supermarkets and cooked in the apartment a few times. Plenty of closet space in the double bedroom. We had hot water in the shower anytime we used it. The beds were all very comfortable. There were extra pillows/duvets in the closet. Allocated one bath, one face and one hand towel each, per person. Washer available in the apartment, no dryer. Wifi was good. Note that trash is a bit of an issue, as you cannot use the residents' garbage cans in the building. Maria explains this and everything else in her emails/messages.
We enjoyed our stay very much and recommend the apartment as a base in beautiful Rome.
