Carmen was very prompt in all contact and gave precise information on how to find her. The apartment is simply a few hundred years from the main railway station and accesses all transport links easily. Although not in the most obviously fashionable location it is actually very safe and surrounded by all you could need by way of multicultural feeding, in or take away.
The apartment is exactly as described and a provides a cost effective base from which to explore this otherwise expensive city. The room is well equipped and very clean, the bed is very comfy and the bathroom well appointed. The hot water supply idiosyncracies are easily overcome and add to the charm; as does the lift accessed from the half landing and of the old genteel establishment sort - but is perfectly functional.
Carmen supplies good advice and has tourist maps and guides aplenty for any use. Her invitation to dinner was most welcome and her cooking excellent despite her protestations.
I would use this facility again if I ever built up courage to visit Rome again.
Thank you Carmen
