The appartment was bigger than I expected, very nice and in a calm neighbourhood (although the neighbours can be pretty noisy in the evening, I would suggest to bring earplugs if you count on sleeping early). There are enough buses to the centre so well situated. The host is very quick to answer if you have questions. Don't forget there is a tax to pay now (official Roma City tax) in addition to the total price. Armando told me just the day I arrived so I wasn't very pleased about that. Overall it was a good stay despite the bad weather.
