we liked the place a lot, it's modern, beautiful, has 3 bathrooms, good beds, a great location just a few steps from piazza navona!
we had problems with the heater and the hot water, but marco came immediately and made everything work :-)!
since it is in the middle of the city, it is not the most quiet place, those with very sensitive ears should bring earplugs for a good sleep. but others may not be disturbed at all, thats very individual.
we also ordered the airport taxi via marco and andrea's tourist-office, they were very kind, everything worked out perfect!
Wlan worked super.
