Sylvia and Marco were very friendly and helpful hosts and their apartment is clean and pleasant. The kitchen is perfectly adequately equipped with utensils, complimentary coffee etc. There was a strike by metro drivers on our second full day in Rome and they tried very hard to get us a taxi into the city - not their fault every one was booked! There was also one evening when the gas supply ran out but they fixed this very quickly, within an hour. They were happy to provide a travel cot for our 15 month old toddler. Overall, we were very pleased with both our hosts and the apartment and enjoyed our stay.
As a separate issue - no reflection on either hosts or the apartment itself - you might want to Google the immediate area and consider just how important it is to you to have restaurants, shops, supermarkets etc. on your doorstep as there are none in the immediate vicinity (although it is only a 5-10 minute walk to the supermarket.) There is a coffee bar and cafe/restaurant downstairs and this seems to cater mainly for the office workers from the downstairs buildings - they are shut on Sundays.
On the plus side, there is a lovely park/nature reserve very close by - good for a stroll on a day when there is a public transport strike!
