We had an amazing stay at Pamela's appartment. Even though we were early arriving, there was someone there waiting for us, and Pamela was very welcoming, polite and helpful, giving us local knowledge not found in the guidebooks. The appartment is very well equipped, and for two of us, there was more than enough space. The bed is extremely comfortable as well.
The roof terrace can't be beaten, 360 degrees and a stunning view of St Peter's Basilica, especially when lit up at night!
I'd have no hesitation recommending either Pamela as a host, or a stay in this appartment.
